[openstreetmap/openstreetmap-website] Add pull request template (PR #4919)

[Tobias]

@tordans commented on this pull request.

I think this is a good template that will make thinks better for some PRs. I certainly does not harm the process, because one can always remove all this very easily when creating a PR that does not fit this schema.

I would also remove the risk section. And make the intro even more explicit on the PR section which is where all the "do squash, do rebase, no merge commits" part is written.
