Add expand_wildcards to _cat/indices and _cat/aliases docs (#56964)

This commit adds the `expand_wildcards` parameter documentation to the
`_cat/indices` and `_cat/aliases` docs, as those APIs now support
`expand_wildcards`. Additionally, clarifies the `expand_wildcards` docs with
respect to hidden indices.
