Build/Test Tools: Fix Performance Test workflows on release branches.

This fixes an issue after [59170] that was causing the Performance Test workflows to fail on older branches since the `CODEVITALS_PROJECT_TOKEN` input value was marked as required but was not being passed.

This is a follow-up to [59214] and [59215].

Fixes #62153.
