[FR] (gazelle) Use specified python version to determine whether a module is a stdlib

# 🚀 feature request

### Relevant Rules

At present, we judge whether a module is a standard library through the system interpreter, which is uncontrollable. After https://github.com/bazelbuild/rules_python/pull/1895 landing, we have the ability to use a specific python version of std list in this analysis.

### Description

A clear and concise description of the problem or missing capability...

### Describe the solution you'd like

Maybe two ways:
1. A new directive to specify the python version
2. Read `.manifest.pip_repository` from `gazelle_python.yaml` and find python version from `MODULE.bazel`?

### Describe alternatives you've considered

Have you considered any alternative solutions or workarounds?

Start by reviewing the referenced rules_python pull request 1895, then inspect gazelle_python.yaml, MODULE.bazel, and the .manifest.pip_repository data it mentions. Determine how a specified Python version could reach gazelle's stdlib analysis; done means module classification uses that version rather than the system interpreter.
