Remove unnecessary chdir in container init and start, the invokes seem not necessary.

Hey, the CI is failing because cross now requires rust 1.77.2 and we use 1.77.1. Have opened #2779 which should fix all the CI running issues, so once that is merged, you can rebase on that.

[YJDoc2]

It is merged, so you can go ahead 👍

Hey @Mossaka , I've rebased your branch, I hope that's fine.

It seems like the integration test failed. I am not able to tell if it's related to my changes

Please wait until we investigat this as it could break pseudo terminal.

Sounds good. That's why I made this PR a draft one until we figure out if it's not breaking existing functionality of youki.

I was worried about catching it on the test, but it looks like they were testing it! I want to thank our past selves.

[utam0k]

Sorry, but I've created another PR to fix it.
