Links to all signing keys from src/archive/release-history.md are 404s

Hi everyone, hope you're well.

I'm trying to install an old release of Rust using… a variety of sources. I'm in an HPC environment where rustup doesn't seem to be a good fit. Hope you understand. That is not at issue here. I'm able to get the tarball and I know where to go from there.

The issue is I happened to notice that the links to all the signing keys referred to by https://forge.rust-lang.org/archive/release-history.html (src/archive/release-history.md) are broken.

I'd be happy to do a PR if someone could point me in the right direction.

The most recent version I can find in the Wayback Machine archive is from 2018.

https://web.archive.org/web/20180620064557/https://www.rust-lang.org/rust-key.gpg.ascii

Update: Two can be found on static.rust-lang.org now. This code search in rust-forge offered a clue. The remaining one is MIA.

• https://static.rust-lang.org/rust-key.gpg.ascii
• https://static.rust-lang.org/rust-key-old.gpg.ascii (404, not in Wayback Machine either)
• https://static.rust-lang.org/rust-key-very-old.gpg.ascii

Update 2: rust-key-old.gpg.ascii can't be found on static.rust-lang.org because it's rust-key-old.gpg. So all three keys are available, and I'll do a PR to correct those now.
