Merge #15559: doc: correct analyzepsbt rpc doc

335931df4a rpc: return a number for estimated_feerate in analyzepsbt (fanquake)
a4d0fd026b doc: correct analysepsbt rpc doc (fanquake)

Pull request description:

  Even though `missing` is optional, all its field are also all optional.

  `estimated_vsize` is optional (calculate alongside `estimated_feerate`).

  Make `estimated_feerate` output numeric.
