Find Python after installing it, like Git and Node

Browse Source 
winget installed Python successfully and the very next line reported it
missing. The re-probe only checked `py -3` and `python` on PATH, and a
just-installed interpreter is not on the PATH this session inherited at start
— the same failure Git and Node already had directory probes for. Python
never got them.

Probe the standard install homes before giving up:

  %LOCALAPPDATA%\Programs\Python\Python3*      (per-user, winget's default)
  %ProgramFiles%\Python3*                      (all-users)
  ...\Python\Launcher\py.exe, %SystemRoot%\py.exe

Globbed rather than version-pinned so a 3.13 install is found too, and the
loop body uses %%~D: a quoted for /d pattern carries its quotes through, which
would otherwise mangle every path built from "C:\Program Files\Python312".

This also covers Python installed without "Add python.exe to PATH" ticked,
which is the more common way to end up here without winget involved.
