[collection] Remove instance defaults from docs (#12964)

We don't specify defaults in the module (because it messes up Instance
updates because AWX things we are trying to change things to be the
default).

- Update the docs to remove the defaults that no longer exist
- Update tests to make them pass (oops)
- Fix tangentially related typo in Kind development docs
