Merge bitcoin#25925: doc: add {import,list}descriptors to list of descriptor RPCs

6242314 doc: add `{import,list}descriptors` to list of descriptor RPCs (Sebastian Falbesoner)

Pull request description:

  This PR adds the missing RPCs `importlistdescriptors` ([since v0.21](https://github.com/bitcoin/bitcoin/blob/1420547ec30a24fc82ba3ae5ac18374e8e5af5e5/doc/release-notes/release-notes-0.21.0.md?plain=1#L405)) and `listdescriptors` ([since v22](https://github.com/bitcoin/bitcoin/blob/1420547ec30a24fc82ba3ae5ac18374e8e5af5e5/doc/release-notes/release-notes-22.0.md?plain=1#L175)) to the list of RPCs supporting descriptors in descriptors.md. Also changes the description of `importmulti` slightly to point out that it only works for legacy wallets.
