[Profile indicator] Change profile URL regex

An experiment called SMEI_UNIFIED_PROFILES allows to access profiles
through a new URL which didn't match the regular expression we had for
profile URLs.

This change modifies the regex to match these new URLs.

Example of the new URLs: https://support.google.com/s/community/user/42
