Improves alias list messages after installation.

Fixes #83

[zooba]

With the new name merging algorithm, I get outputs like this:

Tag                Name                             Managed By  Version   Alias
3.14-dev[-64]      Python 3.14.0b1                  PythonCore  3.14.0b1  python[w]3.14[-64].exe, python[w]3[-64].exe
3.14-dev-arm64     Python 3.14.0b1 (ARM64)          PythonCore  3.14.0b1  python[w]3-arm64.exe, python[w]3.14-arm64.exe
3.14t-dev[-64]     Python 3.14.0b1 (free-threaded)  PythonCore  3.14.0b1  python3.14t[-64].exe, python3t[-64].exe, python...

I think I'm going to hide the "w" in py list output as well (without -v).

Hang on. That's py list output, not the message printed at the end of a py install. #83 (which this PR claims to fix) isn't about py list, it's about what's printed after py install.

The output I wanted, after installing Python 3.13, was

Python 3.13 will be launched by python3.exe, python3.13.exe.

Note that the w and -64 variants are not mentioned. As I said in #83, I think they can be left to the documentation to cover.

I don't know whether the code for py list and the code that produces the post-install mesage share the same logic, but if they do, then I'd want py list to show python3.exe, python3.13.exe in the "Alias" column. If that's not acceptable to you (and I don't have a strong opinion on the py list question) then I think we need separate logic for the two separate cases.

They both use the same mechanism now:

$> py install --refresh
Refreshing install registrations.
Active virtual environment will be launched by python.exe and also python.exe
Python 3.14.0b1 will be launched by python3.14[-64].exe, python3[-64].exe
Python 3.14.0b1 (ARM64) will be launched by python3.14-arm64.exe, python3-arm64.exe
Python 3.14.0b1 (free-threaded) will be launched by python3.14t[-64].exe, python3t[-64].exe

will be launched by python.exe and also python.exe

😆 Just spotted this, let me get that too

That last commit swaps the order so that python3[-64].exe sorts ahead of python3.14[-64].exe
