ci: Update node coverage badge to work without games.txt (#156)

* ci: Update node coverage badge to work without games.txt

Fixes #155 using a new node script that should be more robust than the
old shell script.

* ci: Change badge cron time to less common time

By doing at a less common time we should reduce action time usage as
the runners will be under less load.

* Add/Update badge

* ci: Improve node-badge script

* ci: Run node badge action if script changes

* ci: Update node badge path for workspaces

* ci: Revert loading games from index in node badge script
