WinGet adds the relative path directly to the PATH.

Brief description of your issue

I was trying to install a zip+portable package when I encountered an undefined command line alias, and when I checked the user PATH, I found that WinGet added a relative path directly to the user PATH.

Steps to reproduce

git clone https://github.com/DuckDuckStudio/winget-pkgs.git
cd winget-pkgs
gh pr checkout https://github.com/microsoft/winget-pkgs/pull/254394
winget install --skip-dependencies --manifest manifests/d/denglihong2007/CRSim/2.2.0.0/ -l ../Test

Expected behavior

The package can be started using a command line alias.

Actual behavior

> winget install --skip-dependencies --manifest . -l ../Test

Additional Information

If a full path is used the PATH length limit is exceeded.

Start by reproducing the winget install command with the referenced CRSim manifest and -l ../Test, then inspect the attached WinGet log. Trace how portable package installation adds the relative path and command-line alias; done means the alias works without adding an unusable relative PATH entry.
