Matthias Rampke cae4538b3e Docs: state that all regular expressions are RE2. (#3518)
We already mentioned that regular expressions are RE2 for
[relabeling][0], but left open what the regular expression syntax
anywhere else is.

In the querying examples and reference, make it explicit that _all_
regular expressions are RE2.
