docs: state that results are dicts

We also link to the python dict and list classes as a convenience.
Implemented with the intersphinx extension.
Every link that can't be found in our implementation will be looked up

docs: add VALID_RELEASE_TYPES / _STATUSES

I also removed lots of empty lines.
They don't help to read the docs code and don't make a difference in the
output.
