Prevent some CI stages from running on scheduled builds

The goal of this is to ensure the automated PRs that update the
translations from corwdin are working. They are running on a schedule
and the last couple have been failing on steps that aren't needed at
that time (schedule only cares about opening the MR with translations,
all checks will then run on the MR itself)
