Behaviour

Steps to reproduce this issue

1. have a project with a docker build push action on the workflow
2. enable the runs on pull requests
3. have a pull request, the build push action fails with 403

Expected behaviour

The push works with the tag :pr-123 into the target repository

Actual behaviour

Login into registry works with ${github.actor}
Push should go to target repository, but fails.
Error: buildx failed with: ERROR: failed to solve: failed to push ghcr.io/josh-xt/agixt:pr-499: unexpected status: 403 Forbidden

Don't think this is related but the build push action is not configured properly: https://github.com/Josh-XT/AGiXT/actions/runs/5111667183/jobs/9188888271?pr=499#step:15:1

buildkitd-flags does not exist in this action: https://github.com/localagi/AI-pipeline/blob/3007b9776a982006265c1fb85622248c86a6bd25/.github/workflows/operation-docker-build-publish.yml#L214

Should be done in setup-buildx-action: https://github.com/docker/setup-buildx-action#inputs

The push works with the tag :pr-123 into the target repository

Doesn't look possible from a public forked repo as stipulated in GitHub docs. See "Maximum access for pull requests from public forked repositories": https://docs.github.com/en/actions/security-guides/automatic-token-authentication#permissions-for-the-github_token.
