Correct documentation regarding how to restore no feature_states (#83814)
This commit corrects the snapshot creation and restoration docs to
describe the usage of `"none"` to restore no feature states. Previously,
they incorrectly stated that using an empty array would accomplish this,
but specifying an empty array results in the default behavior (rather
than preventing feature state snapshot/restoration).

[[create-snapshot-api-request]]
==== {api-request-title}
`PUT /_snapshot/<repository>/<snapshot>`
`POST /_snapshot/<repository>/<snapshot>`
[[create-snapshot-api-prereqs]]
==== {api-prereq-title}
* If the {es} {security-features} are enabled, you must have the
`create_snapshot` or `manage` <<privileges-list-cluster,cluster privilege>> to
use this API.
[[create-snapshot-api-path-params]]
==== {api-path-parms-title}
`<repository>`::
(Required, string)
Name of the snapshot repository.
`<snapshot>`::
(Required, string)
Name of the snapshot. Supports <<api-date-math-index-names,date math>>. Must be
unique within the snapshot repository.
[[create-snapshot-api-query-params]]
==== {api-query-parms-title}
include::{es-repo-dir}/rest-api/common-parms.asciidoc[tag=master-timeout]
`wait_for_completion`::
(Optional, Boolean) If `true`, the request returns a response when the snapshot
is complete. If `false`, the request returns a response when the snapshot
initializes. Defaults to `false`.
[role="child_attributes"]
[[create-snapshot-api-request-body]]
==== {api-request-body-title}
// Set an attribute so we can reuse these params with anchors
:page-id: create-snapshot-api
// tag::snapshot-config[]
`expand_wildcards`::
+
--
(Optional, string) Determines how wildcard patterns in the `indices` parameter
match data streams and indices. Supports comma-separated values, such as
`open,hidden`. Defaults to `all`. Valid values are:
`all`:::
Match any data stream or index, including <<hidden,hidden>> ones.
`open`:::
Match open indices and data streams.
`closed`:::
Match closed indices and data streams.
`hidden`:::
Match hidden data streams and indices. Must be combined with `open`, `closed`,
or both.
`none`:::
Don't expand wildcard patterns.
--
`ignore_unavailable`::
(Optional, Boolean)
If `false`, the snapshot fails if any data stream or index in `indices` is
missing or closed. If `true`, the snapshot ignores missing or closed data
streams and indices. Defaults to `false`.
`include_global_state`::
+
--
(Optional, Boolean)
If `true`, include the cluster state in the snapshot. Defaults to `true`.
The cluster state includes:
include::restore-snapshot-api.asciidoc[tag=cluster-state-contents]
--
`indices`::
(Optional, string or array of strings)
Comma-separated list of data streams and indices to include in the snapshot.
Supports <<api-multi-index,multi-target syntax>>. Defaults to an empty array
(`[]`), which includes all regular data streams and regular indices. To exclude
all data streams and indices, use `-*`.
+
You can't use this parameter to include or exclude <<system-indices,system
indices or system data streams>> from a snapshot. Use
<<{page-id}-feature-states,`feature_states`>> instead.
[id="{page-id}-feature-states"]
`feature_states`::
(Optional, array of strings)
<<feature-state,Feature states>> to include in the snapshot. To get a list of
possible values and their descriptions, use the <<get-features-api,get features
API>>.
+
If `include_global_state` is `true`, the snapshot includes all feature states by
default. If `include_global_state` is `false`, the snapshot includes no feature
states by default.
+
Note that specifying an empty array will result in the default behavior. To
exclude all feature states, regardless of the `include_global_state` value,
specify an array with only the value `none` (`["none"]`).
`metadata`::
(Optional, object)
Attaches arbitrary metadata to the snapshot, such as a record of who took the snapshot, why it was taken, or any other useful data. Metadata must be less than 1024 bytes.
[id="{page-id}-partial"]
`partial`::
(Optional, Boolean)
If `false`, the entire snapshot will fail if one or more indices included in the snapshot do not have all primary shards available. Defaults to `false`.
+
If `true`, allows taking a partial snapshot of indices with unavailable shards.
// end::snapshot-config[]
// Unset the attribute

[[create-snapshot-api-example]]
==== {api-examples-title}
The following request takes a snapshot of `index_1` and `index_2`.
[source,console]
-----------------------------------
PUT /_snapshot/my_repository/snapshot_2?wait_for_completion=true
{
"indices": "index_1,index_2",
"ignore_unavailable": true,
"include_global_state": false,
"metadata": {
"taken_by": "user123",
"taken_because": "backup before upgrading"
}
}
-----------------------------------
The API returns the following response:
