  Use changelog.d for release notes (#26002)
  
  GHC now uses a fragment-based changelog workflow using a custom script adapted from https://codeberg.org/fgaz/changelog-d.
  
  Contributors add a file in changelog.d/ for each user-facing change.
  At release time, these are assembled into release notes for sphinx (in RST) format, using
  the tool.
  
  New hadrian `changelog` target to generate changelogs
  
  CI job to validate changelog entries for MRs unless skipped with ~"no-changelog" label
  
  Teach sphinx about ghc-mr: extlink to link to MRs
  
  Remove `ghc-package-list` from sphinx, and implement it in changelog-d instead (Fixes #26476).
