Subject: [PATCH] Don't filter non-patch registry version (#9736)

The `SysVersion` registry entry may or may not include the patch
version, so if we encounter a registry entry without a patch version, we
must not assume that the patch version is 0.

```
Name                           Property
----                           --------
3.9                            DisplayName     : Python 3.9 (64-bit)
                               SupportUrl      : https://www.python.org/
                               Version         : 3.9.13
                               SysVersion      : 3.9
                               SysArchitecture : 64bit

    Hive: HKEY_CURRENT_USER\Software\Python\PythonCore\3.9
```

Confirmed the fix manually.

Fixes #9668
