🐈 Task: Merge ersilia sample command with ersilia example command as a flag

[DhanshreeA]

Summary

Refer to batch: https://github.com/ersilia-os/ersilia/issues/1262

Ersilia presently has two commands ersilia example, and ersilia sample, which perform overlapping functionality.

• ersilia sample generates permutations of models and model example inputs, ie it randomly selects a few models from the hub, and generates their example inputs.
• ersilia example generates example inputs for any given model id, or it infers the model id from the presently active model session.

The example command can be extended with a sample_models flag to sample a given number of models, and then generate a given number of example inputs for those models.

Objective(s)

• [ ] De-register the sample command here and here, and remove its source file.
• [ ] Add a flag --sample_models to the example command and implement this functionality if the flag is set by way of using the ModelSampler class as in the implementation of the sample command.
