fixes syntax

[lazybuttrying]

env.reset() returns more value, that is "info"
env.step() returns more value, that is "truncated"

[mokizzz]

Already fixed in the newest code:

minimalRL/actor_critic.py

Line 75 in c8efed8

s, _ = env.reset()

minimalRL/actor_critic.py

Line 81 in c8efed8

s_prime, r, done, truncated, info = env.step(a)

But have not been fixed in other algorithms like a3c.py:

minimalRL/a3c.py

Line 48 in c8efed8

s = env.reset()

minimalRL/a3c.py

Line 55 in c8efed8

s_prime, r, done, info = env.step(a)
