Reinforcement Learning: Examples for DDPG and TD3 with Gymnasium Environments

[tareknaser]

Description:

This PR updates the reinforcement learning examples with the latest Gymnasium Python server. Two significant examples have been added.

DDPG on MountainCarContinuous-v0:

• The agent was trained for a total of 100,000 steps.

TD3 on Pendulum-v1:

• The training was performed for 50,000 steps.

Note: Both examples include locally saved videos that will be utilized in my final GSoC report.
