Gazelle: PEP 723 Support?

# 🚀 feature request

### Relevant Rules

`gazelle`

### Description

With [PEP 723](https://peps.python.org/pep-0723/) approved, should we do something with that with gazelle?

### Describe the solution you'd like

Thoughts:

+ Maybe we read all files and add any PEP 723 deps to an "effective" requirements lock file?
+ Parse the PEP 723 deps and add to the `deps` attribute? How is this different from parsing `import`?
+ might be an alternative to the annotation `# gazelle:include_dep @pypi//foo` within a python file.
+ ???

### Describe alternatives you've considered

None.

首先检查 Gazelle 当前对 Python 依赖项的处理方式，包括导入解析、deps 属性和 # gazelle:include_dep 注解，然后将其与 PEP 723 依赖元数据进行比较。完成此项工作需要就 PEP 723 支持的范围和行为达成一致，并由测试提供支持；issue 未指定任何文件或测试入口点。
