Kim Morrison 91a150939f chore: remove stale release draft notes (#12518) 
The `releases_drafts/` folder contained two entries that were already
covered in earlier releases:

- `module-system.md` — the module system was stabilized in v4.27.0
(https://github.com/leanprover/lean4/pull/11637)
- `environment.md` — the `importModules`/`finalizeImport` `loadExts`
change landed in v4.20.0 (https://github.com/leanprover/lean4/pull/6325)

Discovered while preparing the v4.29.0-rc1 release notes.
