WIP: Bzlmod part the one hundred thirty-fifth

Update tests for Bazel 6 + Bzlmod

Copied the regular expression used to optionally match canonical repo
name prefixes in `buildozer` commands from bazel-contrib#1622. These never failed
when building with Bzlmod and Bazel 7.4.1, but did under Bazel 6.5.0.
