opam does not support nushell

[ferrisml]

My default shell is nushell. I wanted to initialize opam for nushell, but it is rejected as unknown shell.

opam init -y --shell=nu                                     
opam: option '--shell': invalid value 'nu', expected one of 'bash', 'sh',
      'csh', 'zsh', 'fish', 'pwsh', 'cmd' or 'powershell'
Usage: opam init [OPTION]… [NAME] [ADDRESS]
Try 'opam init --help' or 'opam --help' for more information.

Operating system is Fedora 42

There is already a PR open for it if you want to test it: #6330
There is no guarantee that's we'll be able to finish and review it before the next release (there are lots of more urgent PRs) but we can try.

from within nushell execute config nu add load-env (opam env | from json) save and exit.

Thanks a lot. I will close the issue.

No problem, thanks! Let's keep the ticket open until the PR is merged though ^^

Ok, I agree, because after I posted, I saw a different problem and I am not sure it works.
