Rollup merge of #98734 - tmiasko:uninhabited-calls-release-notes, r=Mark-Simulacrum

Update RELEASES.md

Clarify that flow sensitive checks now understand that *visibly*
uninhabited call expressions never return.

The change influences checks of reachable and unreachable code alike,
not just dead code like previous wording would imply.
