Support the Bzlmod

[dkthezero]

I'm working on the new monorepo project based on the existing Cargo project, we decided to use Blzmod instead of the old Workspace. We have applied the hybrid mode but IMO should support Bzlmod by default:

• Use new naming convention: gazelle instead of bazel_gazelle, rules_go instead of io_bazel_rules_go
• Easy to setup

I propose a PR that I have use as local module: https://github.com/Calsign/gazelle_rust/pull/9
