ephemeral: drop due to upstream archival (#398111)

doc/release-notes/rl-2505.section.md

···
 
 - The `electron` packages will now provide their headers (available via `electron.headers`) in extracted form instead of in a tarball.
 
+- The `ephemeral` package was removed due to upstream archival in early 2022.
+
 - [testers.shellcheck](https://nixos.org/manual/nixpkgs/unstable/#tester-shellcheck) now warns when `name` is not provided.
   The `name` argument will become mandatory in a future release.
