Issue with page /start/nix-develop/

[mo8codes]

This copy button copies the text for the Scala development environment, not rust:

Also the edit this page button doesn't work:

It takes me to this link instead:
https://github.com/DeterminateSystems/zero-to-nix/edit/main/src/content/start/nix-develop/.mdx
Which 404's as can be seen in the previous image, this is a problem as it is harder to create a pull request simply fixing the first error.
