Avoid depending on typing_extensions.

[yukikaoru]

While type hints utilize typing_extensions, django-enum does not include typing_extensions as a dependency library. Even if installed, typing_extensions will not be automatically installed.

The only elements from typing_extensions used are get_args and Annotated, but in Python 3.9, both are available in the typing module.
Since django-enum requires Python 3.9 or higher, there seems to be no need to specifically use typing_extensions.

Pull Request Overview

This PR removes the dependency on typing_extensions by migrating from typing_extensions.Annotated and typing_extensions.get_args to their equivalent implementations in the standard typing module. Since django-enum requires Python 3.9 or higher, and both Annotated and get_args are available in the standard library from Python 3.9, this change eliminates an unnecessary external dependency.

Key changes:

• Replace typing_extensions.Annotated with typing.Annotated (using the t. alias)
• Replace typing_extensions.get_args with typing.get_args
• Remove all typing_extensions imports across test files and source code
