[feature request/bazel] integrate GH action for automatic push to BCR on release

There is [this github action](https://github.com/bazel-contrib/publish-to-bcr). Can it be installed by the repository maintainer here so that each release will be automatically pushed to the BCR?

I see that CI regularly tests for Bazel compatibility, but upon merge and release, the `emsdk` module is not automatically pushed to BCR, requiring manual intervention.

The [BCR module](https://registry.bazel.build/modules/emsdk) is outdated and unmaintained, and usually requires a manual PR to land there.

Can we add automatic push to BCR to this repository?
