Micromamba 2.0.1 not honoring system PATH (Windows 11)

[arpitg95]

I recently upgraded to Micromamba 2.0.1 from 1.5.8, and I was not able to launch certain commands from powershell (like notepad or code). Looking a bit into it, I found that Micromamba 2.0.1, after activation, does not seem to honor system's PATH - instead of appending to the existing PATH from OS's environment variables, it overwrites it for the shell, i.e. the effects persist even after deactivation.

Take a look at the shell outputs for both the versions of micromamba.

Update: This issue is already raised in mamba-org/mamba#3405
