check-task-pipeline-bundle-repos.sh check for PRs

Passes the pull request commit id to the
`check-task-pipeline-repo-existence` step to make the validation
consider pull request image references; otherwise the check checks for
images that are have resulted from changes pushed to the default branch.

The URL being checked for existence now checks against the Docker
registry API, the quay.io REST API has no endpoint to check for
existence of tags. Also the non-pull request artifacts are checked for
their correct tag/version now.
