Some work on the README

[fingolfin]

This takes some of #38 into account by reordering and rephrasing some stuff, dropping the minimal example etc.

But not everything is done yet, e.g. the suggestions for step 5 are not taken into account -- partially because I'd like to do this while actually making a release -- e.g. as I recall, there is a delay before one "sees" any progress bars etc., unless one manually reloads, and if that recollection is right, this should also be described... in any case, the text must match what really happens so I don't want to write it blindly right now.

But partial progress is still progress, right? ;-)

The latest version of the instructions look fine.
However, I still do not understand how to achieve a dry run.
My guess is to edit the release.yml file, changing the "default: false" under "dry-run" to "default: true"
before starting the action process. Is that correct - if so, perhaps make that clearer?

Borrowing Max's image from the README: clicking the first checkbox in this menu before clicking 'Run workflow' should do a dry run.

I am planning to add instructions for this in the README as part of #23, but I haven't got around to it yet.

Thanks. I suppose that should have been obvious, but the first box could have been: "dry-run: only create ..."
