`packaging==24.0` is incompatible with `setuptools==78.1.1`

[DanielKongsgaard]

🐞 bug report

Affected Rule

When updating requirements I hit the following error:

 ImportError: Cannot import `packaging.licenses`.
                Setuptools>=77.0.0 requires "packaging>=24.2" to work properly.
                Please make sure you have a suitable version installed.

Is this a regression?

Yes, but I am not sure when it was introduced.

Description

In //python/private/pypi/deps.bzl there is a list of pypi packages with packaging-24.0 and setuptools-78.1.1, which clearly doesn't satisfy the setup tools requirement described in the error.

I have a branch where I have run bazel run //tools/private/update_deps:update_pip_deps to update all the packages, and that seems to work fine, but I can see from the git history that packaging was manually downgraded in commit 309ee59 with commit message:

revert: Updated pip and packaging versions to work with free-threading packages (https://github.com/bazel-contrib/rules_python/pull/2514) (https://github.com/bazel-contrib/rules_python/pull/2584)
This reverts commit https://github.com/bazel-contrib/rules_python/commit/fbf8bc10a466c498fc80c6b58c939a87a8d9e929 (https://github.com/bazel-contrib/rules_python/pull/2514)

Also, update the CHANGELOG about the reverting.

Fixes https://github.com/bazel-contrib/rules_python/issues/908, which is about the `pip-compile` not using the right files
for performing the locking. It seems that the `pip` upgrade regressed
this error.

I don't know if this is still a problem, but if not a simple solution could be to just update all the packages or only packaging to a new enough release.
