Mirrors the miti99bot push step — clones tiennm99/loldle, copies
champions.json into public/, commits and pushes. Gated on
LOLDLE_PUSH_TOKEN secret; step is a no-op when unset.
Replaces the repository_dispatch notification flow. After a successful
champions.json commit in loldle-data, this workflow now clones
miti99bot, copies the file, regenerates champions-data.js via the
project's build script, and commits+pushes to miti99bot main.
Token secret renamed MITI99BOT_DISPATCH_TOKEN -> MITI99BOT_PUSH_TOKEN
to reflect the new scope (contents:write on tiennm99/miti99bot).
After a successful commit of champions.json, send a repository_dispatch
(type: loldle-data-updated) to tiennm99/miti99bot so its sync workflow
pulls the latest data into its loldle module. No-op when
MITI99BOT_DISPATCH_TOKEN is unset.
