Update wp-coding-standards/wpcs to 3.4.1

[obenland]

Updates the locked version of wp-coding-standards/wpcs to 3.4.1, including any transitive PHPCS/PHPCSUtils/PHPCSExtra bumps required by it.

The composer.json constraint already allows 3.4.1, so only composer.lock changes.

Verified locally: phpcs output is identical before and after the update. [. phpcs unchanged: CLEAN(rc=0)]

Part of an org-wide sweep to get all repos onto WPCS 3.4.1.

The two failing checks are repo policy (missing [Type] label and milestone) — I don't have triage rights here, so a maintainer would need to add them. Suggest [Type] Enhancement + Infrastructure and the performance-lab n.e.x.t milestone. All functional checks pass.
