James Rodewig 386fb16409 [DOCS] SQL: Update link for supported regex in RLIKE docs (#55830)
The`RLIKE` function docs points users to [Java’s Pattern class doc][0]
for regular expression syntax. However, these docs include shorthand
character classes, such as `[\d]`, `[\s]`, and `[\w]`. These character
classes are not supported in Elasticsearch, which may confuse users.

This updates the SQL `RLIKE` docs to refer to the ES [regular expression
syntax docs][1], which only documents supported syntax.
