Misplaced NEWS entries

Bug report

I noticed a common error -- a NEWS entry for changes in the stdlib can be added in the "Core and Interpreter" section instead of "Library".

Some errors I only noticed after merging a PR and creating backports, in which case I fixed them immediately. But I reviewed NEWS entries since 3.15 and found many others. I am sure there are errors in older entries.
