d75ee3a9e1 docs: fixes for Release Notes v22.0.0 and v21.0.0 (Konstantin Akimov)

Pull request description:

  ## Issue being fixed or feature implemented
  I noticed that we announced in current release new RPC `quorum platformsign` which has been actually released with v21.
  Though, in release notes for v21 it has a wrong name.

  ## What was done?
  Removed `quorum platformsign` from v22 release notes; fixed name in v21.
  Also mentioned build for Freebsd and minor typo `s/MN_R/MN_RR/` with name of forks on regtest.

  ## How Has This Been Tested?
  N/A

  ## Breaking Changes
  N/A
