gazelle not working with windows

[chrislovecnm]

🐞 bug report

Affected Rule

Gazelle is not finding the default Python interpreter when configuring gazelle with bzlmod.

Is this a regression?

No.

Description

When generating the modules_map for gazelle, the rules are not finding Python in its default path.

ERROR: An error occurred during the fetch of repository 'rules_python~override~pip~pip_typing_extensions':
   Traceback (most recent call last):
        File "C:/users/chris/_bazel_chris/r4du22do/external/rules_python~override/python/pip_install/pip_repository.bzl", line 658, column 53, in _whl_library_impl

                fail("python interpreter `{}` not found in PATH".format(python_interpreter))
Error in fail: python interpreter `python.exe` not found in PATH

🔬 Minimal Reproduction

See #1155

🔥 Exception or Error

Run:

bazelisk.exe build //:modules_map

Part of the error will end with:

This is because bazel in windows has enable runfiles disabled by default. Turn it in and voila. Add it to your .bazelrc
