💡 [REQUEST] - Port TorchRL `Pendulum` tutorial from pytorch.org/rl to pytorch.org/tutorials

[vmoens]

🚀 Descirbe the improvement or the new tutorial

For historical reasons, TorchRL privately hosts a bunch of tutorials.
We'd like to bring the most significant ones to pytorch tutorials for more visibility.

Here is the tutorial.

Environments (or simulators) are a core part of many RL algorithms. The OpenAI Gym API has had a great success in the past years and paved the way for RL researchers to quickly test ideas with an easy-to-use tool.
As a PyTorch-first library, torchrl aims at being (1) oblivious to the simulator (gym or other), (2) rely on pytorch for anything we can in the simulation process, (3) a good integration within the library and (4) a coverage of many different types of environments (simulators, real-life hardware, model-based, RLHF etc). For these reasons, TorchRL propose its own class of environments. We have a dedicated tutorial that covers their design and usage: you can help us port it where it belongs!

Steps:

1. Port the tutorial from the RL repo to the tutorials repo.
2. Fix any formatting issues or typos.
3. Make sure the tutorial follows the tutorial template (template_tutorial.py)
4. Preserve the original author
