Revert "Build: pass PATH environment variable to Docker container (#10133)"

This reverts #10172 & #10133

Looks like we need to run pre-commit

[stsewd]

We may want to run pre-commit in another commit, and do a merge commit instead of squash+rebase, to avoid any conflicts when merging main into our release branches.

I'm not really sure how to make this pass, it passes locally:

-> pre-commit run --files readthedocs/doc_builder/environments.py
check for added large files..............................................Passed
check python ast.........................................................Passed

@ericholscher that's because the commit is already done, you can run pre-commit run --from-ref main --to-ref HEAD

[ericholscher]

This was merged into main manually 👍
