Use docker/metadata-action@v5 in workflows

[echoix]

To unblock dependabot updates, and facilitate some other PRs, we would need to update all our workflows to use docker/metadata-action@v5 and specify a new naming scheme for our temporary built (non released) images tags in PRs.

Dependabot checks fails for now at the step of building images, since we manually build the image tag name include the author name. Dependabot has dependabot[bot] as the author name, which is invalid.

I suggest we use tag names that are made by default and easiest to create, like including pr-3093 for PRs, and having the specific suffixes for the different images that we need done.
