Cut a release including bzlmod support

It would be very nice if a new release could be tagged now that support for bzlmod has been added. It can then be added to the Bazel Central Registry, which will make it easier for other modules to depend on rules_perl. If a release is tagged, I can do the work to submit a pull request to BCR to have it added, though longer term it would be good for this to be automated.

Start by reviewing the repository's existing release process and the changes that added bzlmod support; no specific files or entry points are named in the issue. Done means a new release is tagged so the issue author can submit rules_perl to the Bazel Central Registry.
