rustc 1.51 and cargo 0.52 required by firefox 91

[Olivier Tilloy]

Firefox 91+ will require rustc 1.51 and cargo 0.52 to build¹.

The beta phase for Firefox 91.0 begins on 2021-07-08 and release candidates will be available from 2021-08-05.

We will need these in impish and all supported releases except groovy (which by then will be EOL): bionic, focal, hirsute.

[Ian Douglas Scott (ids1024)]

This released on Bionic and Hirsute a week ago, but Focal still has Rustc 1.47.0. Is there a reason for that?

(1.51 also doesn't seem to be in any of the Focal branches on https://code.launchpad.net/ubuntu/+source/rustc, but I don't entirely know how the workflow for package releases works.)

[Michael Hudson-Doyle (mwhudson)]

I assume that's just an oversight. https://launchpad.net/~ubuntu-mozilla-security/+archive/ubuntu/rust-updates/+packages is where the packages are copied from, and that has focal.
