Reproducible example

pixi self-update
  × pixi is not installed in the default location:
  │
  │ - Default pixi location: /home/me/.pixi/bin/pixi
  │ - Pixi location detected: /data/home/me/.pixi/bin/pixi
  
pixi --version
pixi 0.25.0

Issue description

I've got a symlink from /home to /data/home. this breaks the above check.

Expected behavior

The check should probably canonicalise both paths before comparing.
