Fix workflow runs on PR from other contributors

[dickwolff]

When a contributor opens a PR, the GitHub workflows do not run. I have to approve each run manually. When I run a workflow (eg. testing), the run fails on adding the test results on the PR:

The testing workflow needs to be able to run on any PR, and publish the results on the PR.

I don't want the Docker pipeline to run though, so not any image will be pushed to Docker hub.

Tried setting workflow permissions to r/w (as stated here, but still doesn't seem to work.

As stated in this thread, changed pull_request to pull_request_target and now it works on forked repos!

Did not solve the issue. Need to look into more.

Created a possible fix in #59 but will have to wait for someone else to open a PR to verify this.

Still an issue. #67 failed with Resource not accessible

Reverted back to marocchino/sticky-pull-request-comment, but added check in step that only PR created by @dickwolff will add coverage. Not ideal but don't have a better solution. The tests run, which is the most important thing. Closing.
