[gcharest]

OWASP, A11Y and LightHouse all have been failing since v3 of upload-artifact action has been deprecated.

OWASP and Lighthouse have different root cause.

A11ywatch issue is related to the action's latest release not including the upload-artifact commit with the v3 to v4 fix. Pinning the proper commit to update the action.
