Nit: move above and sort

Also the release notes are missing.

make static and reorder imports

This PR doesn't contain any change to the release notes. I'm not sure why we would want to warn people about this, it's not breaking any existing behavior, or fixing any bug they'd waiting on, and is not a very major change.

My understanding is that we add to the release notes everything that is user facing, and adding a new RPC is part of it.
BTW it's part of the release notes for core as well (see 0.17.0: https://github.com/bitcoin/bitcoin/blame/master/doc/release-notes/release-notes-0.17.0.md#L271).

This files doesn't exist (yet) in our codebase, I think you can simply remove the sentence.

So I dug into it, the release note was added in another patch and there are some patches in between. IMO the best course of action is to either leave it there and add the descriptor later, and accept the state will be jenky for a handful of commits.

Remove release notes. Will add them back when backporting PR13697 and PR14096
