Trigger a Weblate reset after pushing translations

After we have told Weblate to push all of its pending commits, it should
forget about them.

The reason is that we may revert some code samples, and when the
translations PR finally squash-merges its way onto `main` and gets back
to Weblate, it will see a conflict with its own pending changes.

By resetting, it will forget about its own pending changes, and think
we are just great upstream translators!
