Bug 1883651 - turn off cron and workflows on main (#5898)

* Bug 1883651 - turn off cron and workflows on `main`

Only keep the geckoview bump (for now), to still pick up mozilla-central
changes over the weekend.

* Bug 1883651 - move import-l10n to beta branch, remove sync-strings workflows

For the 124 beta cycle, we'll import strings directly to that branch,
since main will no longer be getting updates after the migration to m-c.
