np.int is deprecated

[pseudo-rnd-thoughts]

Im part of the dev team on PettingZoo.
We were through our CI trying to reduce the number of warnings and spotted this warning

test/pytest_runner_test.py: 99 warnings
test/unwrapped_test.py: 6 warnings
  /opt/hostedtoolcache/Python/3.7.13/x64/lib/python3.7/site-packages/rlcard/games/doudizhu/game.py:40: DeprecationWarning: `np.int` is a deprecated alias for the builtin `int`. To silence this warning, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
  Deprecated in NumPy 1.20; for more details and guidance: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

Would you be able to fix the warning line, thanks

Hi. It seems that the latest release (1.0.7) does not contain this fix.
