Refactor V2 tests to tests_version2 and add V2/V3 documentation READMEs (#788)

* fix(docs): update references to tests and paths for version 2

* feat(docs): add documentation and examples for BrainPy 3.x

* fix(deps): update brainstate version to 0.2.0 in requirements
docs: update documentation links for BrainPy 3.0 and 2.0

* refactor: simplify dtype assignments and remove unused tests

* chore: update changelog for BrainPy 3.0.0 release and improve context handling in currents.py
