Proposal: Support ability to force the docker build and push workflow to push images

[chatton]

I am working on writing an E2E test using knuu, but dev flow currently requires a PR be merged to main or a release branch before any images are actually built an pushed.

In celestia-app it is currently possible to use workflow_dispatch to trigger the reusable_dockerfile_pipeline workflow, however the actual build and push of the image is skipped due to the issue mentioned above.

It would be nice to be able to trigger builds of development images. A simple solution would be add an extra input to the workflow which would be propagated down to trigger the build & push, and would be set via the workflow_dispatch input of the calling repo.

All you should need to do is open a PR. The PR can even be in draft. You don't need the PR to be merged to build amd images.
