chore: add new partitions and regions (#30737)

Note that the docstring in `aws-entities` states that the regions are
added in the order they went live. For several, that was not accurate so
I reordered them. This is unlikely to matter but I made the change so
that the documentation there would be factually correct.

Not all of these regions/partitions are live yet, but they have been
announced [here](https://aws.amazon.com/blogs/aws/category/regions/)
