fix(gazelle): Use dougthor42's go-tree-sitter via replace instead of modifying names

[dougthor42]

Fixes #2630.

In #2496 we added support for Python 3.12 syntax using the less-than-ideal method of "fork and rename everything". This turned out to be a Bad Idea ™️ for people who happened to be using smacker/go-tree-sitter as a direct dependency.

This PR effectively reverts #2496 and replaces it with a more correct way of doing go module forking: the replace directive for go.mod.

Special thanks goes out to @jbedard for raising the issue and for continuing to poke me to fix it!

If we look at #2496 plus this PR, the net diff to get Python 3.12 support is approximately¹:

Footnotes

1. Manually generated; ignores the Python 3.12 test ↩

[jbedard]

That looks right, but the CI error seems to be the "fatal error: ../array.h: No such file or directory" error which required the custom BUILD files? Yet only bzlmod is failing? :/

[dougthor42]

The issue is that go.mod replace is only respected for root Bazel modules:

The root module can override certain aspects of the dependency resolution performed by the go_deps extension.

So while the WORKSPACE stuff works, and the unit tests in gazelle/python/testdata pass, anything that uses rules_python_gazelle_plugin as a bzlmod dependency (like the examples dir), fails.

[jbedard]

So this solution won't work? There must be another way to do this other then today's solution 😢

[jbedard]

@dougthor42 how about adding to the default_gazelle_overrides.bzl. I've never investigated it before so I'm not entirely sure if that's right, and it seems to be in a "bzlmod" directory.

Can we just contribute to that file to get gazelle properly generating BUILDs for go-tree-sitter instead of doing any of this forking/patching?
