PaC fails to trigger pipelines for commits generated by github-actions[bot]

In HACBS-150, I'm setting up a git repo with a github action that commits and pushes to a build branch every 15 minutes. I want to use this to trigger pipelines and (eventually) I want to measure the success rate of those pipelines as a proxy measurement for reliability of our system.

When the github action pushes to the repo, it authenticates as a "github-actions[bot]" user. This username is sent to PaC as part of the payload from github. PaC fails to create the pipelinerun because it fails to create a label with the "[" and "]" characters in it.

$ oc logs deployment/pipelines-as-code-controller | grep "is invalid" 

Unknown macro: {"severity"}

Any recommendations?
