This imports #147010 into a PR in preparation for the release next week. It also imports a subset of the Cargo release notes (cc @rust-lang/cargo).

Hi relnotes-interest-group, this issue/PR could use some help in reviewing /
adjusting release notes. Could you take a look if available? Thanks <3

Per discussion on Zulip (I think you were in the thread), this may cause people to want to alter their editor/terminal's color schemes. I definitely did.

I'm open to dropping it or moving it to the Cargo section, but that's my rationale.
