GONRG-6027: Enable containerize-bootstrap jobs

Enabled osdu-gcp-containerize-bootstrap-gitlab and osdu-gcp-containerize-bootstrap-gcr jobs. OSDU_GCP_ENABLE_BOOTSTRAP variable is added only in containerize jobs to disable .verify_bootstrap job that is failing because legal-bootstrap is not deployed by default.

   OSDU_GCP_SERVICE: legal
   OSDU_GCP_VENDOR: gcp
-  # FIXME: bootstrap is disabled by default, should be changed to "true" after all requirements are collected
