Add 1.89 beta-accepted changes to changelog (#15534)

https://github.com/rust-lang/rust-clippy/issues?q=state%3Aclosed%20label%3Abeta-accepted

Those were missed in the prior backport. The two beta-accepted issues
that were not added were done as reverts of the prior changes they
fixed. So no reason to add them to the changelog.
