Having them at each commit is counter-productive, first because these
builds take so long and second because there seems to be quite few
Windows runners. So we end up constantly waiting for CI jobs from
previous commits (so we are just constantly waiting).

This is resource over-usage. So instead, I'll just set this in scheduled
jobs. For release preparation though, we'll have to set up a workflow
later to trigger these jobs off-schedule/on-demand (I can see there is a
Gitlab interface to do this), but this can wait for when the installer
is fully generated by the CI anyway.
