[beta] Backport "Less greedily parse [const] bounds"

[fmease]

Backport of #146422.
Following https://forge.rust-lang.org/release/backporting.html#beta-backporting-in-rust-langrust.

Not part of some hypothetical future backport rollup because we're under time pressure as release procedures will commence very soon: https://forge.rust-lang.org/#current-release-versions, https://forge.rust-lang.org/release/process.html.

Only a few people are even aware of the process, but this is actually something anybody can do.

A reviewer (typically from the release team) needs to verify that the backport looks correct and that it’s submitted to the beta branch. […]. If the author of the PR has r+ rights, and has not made significant changes while backporting, they can also self-approve the PR.

Change the milestone to the correct value for the beta release.
Remove the beta-nominated label. This indicates that the backport has been completed.

Applied.
