Update requirement specification

[oberbichler]

• I have added a news fragment under changelog.d/ (if the patch affects the end users)

Summary of changes

• Update documentation for pipx run with dependencies in a local script (resolves pipx fails to run script with dependencies. #1227)

Test plan

Tested by running

# test.py

# /// script
# dependencies = ["requests"]
# ///

import sys
import requests
project = sys.argv[1]
pipx_data = requests.get(f"https://pypi.org/pypi/{project}/json").json()
print(pipx_data["info"]["version"])

with

pipx run test.py

Thanks for updating this. Could you please add a doc news fragment according to our contribution guidelines?

Please also mention that the requirement specification syntax comes from the inline script metadata specification.

Please also mention that the requirement specification syntax comes from the inline script metadata specification.

As per @katrinafyi in #1244:

If you have a script `test.py` that needs 3rd party libraries,
you can add [inline script metadata](https://packaging.python.org/en/latest/specifications/inline-script-metadata/)
in the style of PEP 723.
