[CI] use popd/pushd instead of cd

[leseb]

Replaced instances of cd with pushd and popd to manage directory changes, ensuring the script maintains a clean and predictable directory state. This change improves readability and maintainability by using directory stack operations, allowing easy return to the original directory after performing tasks in different directories.

I don't think it's worth fixing the problems. These scripts have not been used in our testing pipeline for a while. We have completely offloaded torch inductor tests to Meta

@Jokeren, should we remove the tests, then? That way, it's clear for the future that no one should attempt to modify them.

[Jokeren]

Sure
