[DOCS] Update version-specific documents with restrictions on fuzzy matching when using synonyms

[rwaight]

Description: Back-port the documentation updates from PR #40783 to version specific pages. The reason for this issue is that we’ve updated the master docs page of the Fuzziness section under Match Query which states:

Note that fuzzy matching is not applied to terms with synonyms, as under the hood these terms are expanded to a special synonym query that blends term frequencies, which does not support fuzzy expansion.

However, this paragraph is only in the master page, not in any version specific page (i.e., it is not mentioned in the equivalent 6.2 docs page. With that said, based on issue #25518, this appears to be applicable to all versions.
