Nit: Fix links in NEWS.md by running NEWS-update.jl

[NHDaly]

Fixes the out-of-date hyperlinks on NEWS.md.

It looks like that step was missed on #30061 and #30200

It's really only necessary to do right before a release, but it's also fine to do earlier.

(We don't generally do it in the PRs themselves because it creates lots of spurious conflicts between PRs. But it is fine to have occasional separate PRs just to update the links.)

[NHDaly]

Ah, makes sense. Thanks for explaining that, @stevengj.

Should i remove that step from the CONTRIBUTING.md? It currently says:

The news item should cross reference the pull request (PR) parenthetically, in the form ([#pr]); after adding this, run ./julia doc/NEWS-update.jl from the julia directory to update the cross-reference links.

Yes, it should probablybe changed to something like:

The news item should cross reference the pull request (PR) parenthetically, in the form ([#pr]). We periodically run ./julia doc/NEWS-update.jl from the julia directory to update the cross-reference links, but this should not be done in a typical PR in order to avoid conflicting commits.

Thanks @stevengj. I've changed that here: #30482
