Run main script also on PR

[teutoburg]

• Only run on non-draft PRs
• Don't run Slack bot notification for PRs

Fails because #30 isn't in yet. Although I'd prefer merging this first, to get a nice green check on the other one. But either way will be fine...

Requiring a user to manually start the job was deliberate, because it takes two hours.

But perhaps having the job not run for draft PRs is good enough. It is nice to get a checkmark yes.

We can always change it back.

It just occurred to me that the main workflow can create a PR if there's newly downloaded data (indeed the original purpose of this!), could this mean we might end up in a recursion here? Maybe only trigger this with a specific label or give the auto PR a label and don't fire when that's there...

Oops; thanks.
