Deep Q network example missing dependency

[cadop]

I am not sure how this example can work, and perhaps there should be a warning at the top mentioning the required dependencies: https://keras.io/examples/rl/deep_q_network_breakout/

Using the View in Colab button doesn't work, since breakouts is not installed.

Running locally is confusing, because breakouts requires/tries to install mujoco, which is pretty expensive.

*edited, actually it seems to run (maybe?) even when pip install breakouts ends with an error on mujoco, but this is pretty confusing still. Ideally docs can warn users.

You can install the breakout gym environment by running pip install gym[atari]==0.21.0 pip install gym[accept-rom-license]==0.21.0
