feat: Default pagination recommendation now cursor-based instead of o…

…ffset (#63)

PR for discussion at
#25
- [X] Change pagination recommendation to cursor-based
- [X] Include language that all APIs **MUST** include cursor-based
pagination
- [ ] Add additional documentation about the use case of API sorting +
pagination types
- [ ] Add additional documentation about how Offset and Cursor
pagination is used at the same time

@mkokotovich and @travisgosselin - maybe you have some recommendations
on the additional documentation items?

Also, we had discussed including language that all APIs must (as a
requirement) implement cursor pagination. Does that make sense for
simple/static APIs as well?
