Run sphinx-lint on Misc/NEWS.d/next/

[hugovk]

Follow on from #105750.

Before that PR, we used to run sphinx-lint on Doc/ and Misc/NEWS.d/next/

After, we only ran sphinx-lint on Doc/. I think leaving out Misc/NEWS.d/next/ was an oversight on my part, let's add it back.

In the meantime, a handful of NEWS warnings had slipped through, this PR also fixes them.

LGTM.

Although I do not see a difference in some files. Why are they marked as different?

[hugovk]

They were "No newline at end of file":

The 3.12 backport will only need the first commit, I'll backport it manually.

Looks good, a few optional suggestions:
