Rollup merge of rust-lang#135934 - ferrocene:pa-1.81-relnotes, r=Mark-Simulacrum

Include missing item in the 1.81 release notes

It was pointed out to me that when I prepared the CVE-2024-43402 fix in the stable branch, I added the release notes in the stable PR (rust-lang#129960), but I forgot to do so in the beta or nightly PR. Because of that, the relnotes line only appeared in 1.81, and disappeared afterwards.
