[BUGFIX] Use correct path variable on Windows

There is a difference between Apache and CLI exposing global path
configuration on Windows Systems. The CommandUtility uses the global
path to initialize an internal path storage for possible command
resources. The patch ensures both possible keys on Windows systems are
taken into account to resolve possible application locations.

Resolves: #83234
