docs: move changelog to docs/changelog, drop the docs/info folder

Relocate docs/info/changelog/ -> docs/changelog/ (docs/info held only the
changelog) and update all references: the toctree, README + MAINTAINERS links,
make_release.py, and the make-release skill.

 A PR merged into a *feature branch* (rather than master) is folded into its parent top-level PR and won't appear on its own — intended (review follow-ups aren't double-listed), but make the parent's changelog bullet reflect the final merged state. This is also why a date-based `gh` query returns *more* numbers than this set: those extras are the prior changelog PR plus these sub-PRs.
