fetch_pip_metadata fails if the pwd contains a space

[bddvlpr]

If the project is nested in a parent directory that contains a space, it will fail as the space will separate the path and thus will be interpreted as two (or more) parameters to fetch_pip_metadata.

Can be reproduced by renaming the python-project (or any parent directory) to python project and running nix run .#default.lock
