Documentation

In section 4.8.2 of the docs (Shebang Lines), it is stated that: "Any of the above virtual commands can be suffixed with an explicit version (either just the major version, or the major and minor version)."

This sentence refers to the 4 virtual commands: /usr/bin/env, /usr/bin/python, /usr/local/bin/python, python.

This is correct for the last 3 virtual commands (e.g. /usr/bin/python3.12 works), but not for /usr/bin/env.

Specifically, using either the major version (e.g. "/usr/bin/env python3") or the major and minor version (e.g. "/usr/bin/env python3.12") in the shebang line of a .py file, then calling the .py with the windows launcher, results in the following error: "Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases."

Simple solution: change the relevant sentence in the docs to exclude /usr/bin/env: "Any of the above virtual commands (apart from /usr/bin/env) can be suffixed with an explicit version (either just the major version, or the major and minor version)."
