gh-92611: Clarify planned removal version in PEP 594-deprecated modules (GH-92793)

As discussed in #92611 and #92564 and as a followup to PR #92612 , this 3.11+ only PR uses the proper `deprecated-removed` role for the modules deprecated by PEP 593 (PEP-594) to clearly indicate to users that a removal version is planned and what it is, so they can prepare accordingly or voice any unanticipated impacts.

Related to #92792 ; if we decide to backport that PR, the upgrade to using `deprecated-removed` on those functions can be moved to this one.
