For Thunderbird update-verify-next jobs, a new regex is needed in update_verify_config.py:INCLUDE_VERSION_REGEXES.

Thunderbird release versions do not have an "esr" suffix even though the repository is named comm-esrXX. This means that the "esr91-next" regex would not match. (UVC uses the "nonbeta" regex which also does not work.)

The update-verify-next test is new in Thunderbird 91. Since Thunderbird versions
do not include the esr suffix, a separate regex is needed.

Backed out for causing linting failures.

Beta/Release Uplift Approval Request

• User impact if declined: No user impact, this affects UpdateVerify tests only
• Is this code covered by automated tests?: Yes
• Has the fix been verified in Nightly?: No
• Needs manual test from QE?: No
• If yes, steps to reproduce:
• List of other uplifts needed: None
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): Adds an additional regex for version detection that will be used by Thunderbird 91 to run the update-verify-next set of tests. Should have no impact on Firefox as the regex is used only when selected.
• String changes made/needed: no
