[FEATURE] Add Video Logging during training

It would be really nice to log videos of agents' behavior during and after training to TensorBoard.

#### Proposed Solution:

1. Add logic to the existing Mava/Tensorboard logger class to handle the collection of RGB frames.
2. Call this new video logging function from the logger class during the evaluation phase of the algorithm.

Start with the existing Mava/Tensorboard logger class and trace how it is used during the algorithm's evaluation phase. Identify how RGB frames can be collected and passed to TensorBoard, then verify that agent behavior videos are logged both during and after training.
