fix: Python publishing fails on some Python distributions (#4776)

Our recent `jsii-pacmak` release contained an update to `twine` which exhibits a failure when combined with specific versions of `packaging`.

When reading the [bug thread](pypa/twine#1216) the root cause seems to be `setuptools`, but the workaround seems to depend on the installed version of `packaging`.

`twine` declares a dependency on `packaging>=24.0.0` and the bug doesn't appear if `24.2` is installed. As a result, the problem shows on Python distributions that come with `[email protected]` or `[email protected]` preinstalled.

If an older version or no version of `packaging` is preinstalled then `pip` will install a fresh copy and it will pick `24.2`, but older versions match the declared version range and the pre-existing version will be used, which leads to the problem.

To solve, add the required minimum version of `packaging` to our own dependency file.
