Mention dot-prefixed patterns in hidden index docs (#81464)

Browse source 
The hidden index docs did not mention that dot-prefixed patterns default
to matching hidden indices. This PR adds a note explaining the behavior
and why it's like that.

@ -177,6 +177,11 @@ For most APIs, wildcard expressions do not match hidden data streams and indices
by default. To match hidden data streams and indices using a wildcard
expression, you must specify the `expand_wildcards` query parameter.
Alternatively, querying an index pattern starting with a dot, such as
`.watcher_hist*`, will match hidden indices by default. This is intended to
mirror Unix file-globbing behavior and provide a smoother transition path to
hidden indices.
You can create hidden data streams by setting `data_stream.hidden` to `true` in
the stream's matching <<indices-put-template,index template>>. You can hide
indices using the <<index-hidden,`index.hidden`>> index setting.
