news.toml: Remove paragraph tags left-over from conversion.

[debdrup]

Summary

The AsciiDoc conversion, out of necessity, was rather conservative in
removing paragraphs. However, this leaves some entries with tags and
some without tags.

Test Plan

Ran make

[debdrup]

The alternative to this is, of course, to wrap everything in paragraph tags.
The advantage of this is that it won't be necessary to include <br /> tags for when multiple things happen on the same day, but I lean towards that being easier to do, than wrapping everything in each own paragraph.

Go ahead.
