Create deploy key for crates.io

[jdno]

@Turbo87 reported the following in Zulip:

rust-lang/crates.io#7648 implemented support for automatic snapshot archival after git index squashing. I just tried it out, but unfortunately it failed with:

Permission to rust-lang/crates.io-index-archive.git denied to deploy key

Can we extend the permissions of the SSH key to the archive repository? Alternatively, can you give me a deploy key for the archive repo?

A brief investigation revealed that we need to create a new deploy key so that crates.io can access the repositoy.

is this still relevant or can we close this issue? 🤔

[Turbo87]

yes, it's still relevant, though AFAIU @pietroalbini feels strongly that this should be implemented with GitHub apps instead. I'm personally not convinced yet whether it's worth the complexity though.

Personally, Id' be fine unblocking this in the short-term by creating a deploy key and then adding a new issue to the backlog to review all deploy keys in the organization and see how we can move them to private GitHub Apps.
