INP001: Skip files with PEP 723 inline script metadata

[konstin]

I have a single Python file in a directory with a PEP 723 inline script header at the top of the file:

# /// script
# requires-python = ">=3.12"
# dependencies = [
#     "httpx>=0.27.2,<0.28",
#     "packaging>=24.1,<25",
# ]
# ///

Similar to #8690, INP001 should skip such files: They are not meant to be imported, but meant to be run as standalone scripts with uv run folder/my_script.py or pipx run folder/my_script.py.

Good call.
