DM-32843: v23.0.0 release notes

[timj]

Checklist

• ran Jenkins

[timj]

@TallJimbo no need to look at every entry. My main request is to consider:

• Is it worth maintaining separate registry and datastore entries?
• Should we combine misc and other?

My intent is to backport this to main (which will remove all the v23 news fragments from main).

[TallJimbo]

I'd vote for merging other and misc, and I don't think the separation of registry and datastore entries is useful.

Any idea why some entries have ticket links and others do not?

[timj]

I think they all have ticket links. Lines that don't are because the link only appears at the end of the entry and some news fragments are multi-line.
