This moves the bulk of the upgrade information into the consolidated upgrade guide, but leaves the primary upgrade topic in place as a cross reference.

Documents `archived.*` persistent cluster settings and index settings.
These settings are commonly produced during a major version upgrade.
Closes#28027
* Improve docs for pre-release version compatibility
Follow-up to #78317 clarifying a couple of points:
- a pre-release build can restore snapshots from released builds
- compatibility applies if at least one of the local or remote cluster
is a released build
* Remote cluster build date nit
The reference manual includes docs on version compatibility in various
places, but it's not clear that these docs only apply to released
versions and that the rules for pre-release versions are stricter than
folks expect. This commit adds some words to the docs for unreleased
versions which explains this subtlety.
Our upgrade docs don't mention the upgrade assistant, which can be
helpful when migrating across major versions. The docs also don't
mention deprecation logs, which can highlight other functionality that
may change.
This adds a related tip admonition to the upgrade docs.
Updates the supported upgrade path table in [Upgrade Elasticsearch][0]
to include a new row for maintenance releases. For example, this row
covers upgrading from 7.6.0 to 7.6.2.
The new table row only displays for releases greater than n.x.0. For
example, the new row will display for the 7.7.1 release but not the
7.7.0 release.

We do mention that rolling back an upgrade requires a restore from a snapshot,
but it's hidden at the bottom of the "preparing to upgrade" instructions on a
different page from the actual upgrade instructions. This commit duplicates the
preparatory instructions onto the pages containing the actual upgrade
instructions and rewords the point about rollbacks a bit.
A few places in the documentation had mentioned 6.7 as the version to
upgrade from, when doing an upgrade to 7.0. While this is technically
possible, this commit will replace all those mentions to 6.8, as this is
the latest version with the latest bugfixes, deprecation checks and
ugprade assistant features - which should be the one used for upgrades.
