use buildx

[Jomik]

May need to setup buildx before building, to be able to use cache. https://stackoverflow.com/questions/72707357/buildx-failed-with-error-cache-export-feature-is-currently-not-supported-for-d

Buildx is the default. You don't need to set it up, you need to upgrade the build-push-action.

Check the docs: https://github.com/docker/build-push-action

GitHub Action to build and push Docker images with Buildx with full support of the features provided by Moby BuildKit builder toolkit. This includes multi-platform build, secrets, remote cache, etc. and different builder deployment/namespacing options.

Change docker/build-push-action@4976231911ebf5f32aad765192d35f942aa48cb8 to docker/build-push-action@v5 and you get it automatically.

Also caching is still a horrible idea ;-)

Yah, I thought so too when I set up my action, but the export failed until I added this step 🤔
Maybe outdated, unsure..?
