Can't remove nonexistent orgs from crate owners

[nic-hartley]

Current Behavior

Failed to remove the team <organization> as crate owner: could not find the github team <organization>

Expected Behavior

User <organization> removed as crate owner

Steps To Reproduce

(Note: I haven't actually tried this. I stumbled across it while taking ownership of rest.)

1. Create a GitHub organization
2. Create and publish a crate to crates.io
3. Add the organization as an author
4. Delete the organization
5. Attempt to remove the organization as an author

Environment

• Browser: Mozilla Firefox 116.0.3
• OS: Arch Linux (btw)

Anything else?

(If someone wouldn't mind manually removing the dead org from rest in the mean time, I'd appreciate it!)

Happy to put in a PR about this, it doesn't seem like it'd be a huge change. Though I'd need a pointer to. uh. where in this repo to start looking. it's quite large and intimidating.

This is a duplicate of #1818 so I'm going to close and we can coordinate over there!

@carols10cents Whoops, my bad! Thanks.

I promise I searched. Apparently, poorly enough to miss an issue with the exact same name, but still.
