Git GUI: fix Repository>Explore Working Copy (#4357)

This is a companion PR of prati0100/git-gui#95 Since Git v2.39.1, we are a bit more stringent in searching the PATH. In particular, we specifically require the `.exe` suffix. However, the `Repository>Explore Working Copy` command asks for `explorer.exe` to be found on the `PATH`, which _already_ has that suffix. Let's unstartle the PATH-finding logic about this scenario. This fixes #4356
