Update ADV_STABLE_BASELINES_3.md

Removes the unnecessary resetting of is_success to false (the auto reset could be delayed based on action_repeat, so it's better to specify true or false every time when setting done = true to make sure it's up to date).

 The above snippet will send the information on whether or not the episode was succesful to the Python training server.
 SB3 can use this to report the success rate.

+#### 2 - Set is_success to `true` or `false` when ending the episode
 The condition depends on your use case, for example, here's how we can implement this in the [SimpleReachGoal](https://github.com/edbeeching/godot_rl_agents_examples/tree/main/examples/TestExamples/SimpleReachGoal) env.
 In the `player.gd` script, we just add `is_success` to depend on whether or not the reward is higher than 0:
