Upgrade dependencies (#839)

- Update and pin dependencies to specific versions that support Python 3.7-3.11
- Replace deprecated werkzeug.pop_path_info with wsgiref.shift_path_info
- Use the latest httpbin from psf/httpbin
- Remove unused flask test dependency
- Drop Python 2 and Python <3.7 support
- Ensure greenlet 2 is used for now, as psf/httpbin doesn't yet work with greenlet 3
