Adjust key order in the build workflow

Sort all pre-`steps` keys alphabetically descending. Sorting all keys
alphabetically would be somewhat onerous because the `strategy` key
would come after the `steps` key even though it's configuration
information. We can at least sort everything but the `steps` key in
alphabetically descending order and make the `steps` the last for a
job.
