Initially Ic155bd29d46059832cce970bf60375e7e472eca6 had aimed to remove these
legacy provider names during the Pike cycle. While removing references
to these names in Tempest via Id221414d74af8413084c7935b762f93b7ce43c42 it was
highlighted that this wouldn't be possible until Queens and the eventual EOL of
Newton.
This change simply updates the logged deprecation warnings and adds a
new releasenote highlighting that these legancy provider names will
remain until Queens.
