Make PR template less onerous
Make PR template less onerous

I think no one is reading this because I've seen an increase in draft
PRs. To fix that I've moved the draft statement to the top. I also think
the number of check boxes is a lot and isn't resulting in better PRs
because the length means they are not being read. I removed ones that I
think are repetitive or unhelpful. I wish I could A/B test this...
