Gym 0.21.0 support

[AvivSham]

Hi All,
Thank you for you valuable contribution to the RL community!
I'm working with SB and MinAtar their latest commit requires gym==0.21.0 which creates conflict with SB3. The current workaround is to checkout to older commit and then installing MinAtar.
When do you tend to release a version which supports gym==0.21.0?

Thanks in advance.

One other simple workaround is to install it with --no-dependencies flag, otherwise, you can follow #572
