ci: fan out downstream sync on manual pushes too

Add push trigger (paths: champions.json) so direct edits to
champions.json auto-sync to miti99bot and loldle without needing a
workflow_dispatch. Scraper + commit steps skip on push events (the
data is already committed); sync step runs when either changed=true
from the scraper path OR the trigger is push. Default GITHUB_TOKEN
commits don't retrigger workflows, so no self-loop.
