add Web API FAQ

[FilipeFcp]

Hi all. This is the first version of the Web API FAQ.

Let me know any corrections and suggestions

Nice job as always @FilipeFcp ! I myself learned new things about our API here haha.

One thing I'd add is, for the abort file, you might want to mention that simply cutting off the running of the python file doesn't abort the simulation once it's submitted to our cloud.

Nice job again, it looks well-made for LLMs to learn from it too!

Hi @FilipeFcp! Thanks for creating these FAQs!

• As a general comment, I think we often use "task" and "simulation" interchangeably in our documentation. However, I believe some people can't immediately realize what "task" means. So, I recommend consistently using "simulation" whenever possible to prevent confusion.

• In _faqs/web.load.md it would be interesting to comment on how to retrieve the task_id from a simulation or design_optimization in GUI. Maybe refer the user to that tutorial about downloading and plotting datasets from GUI.

• When you have time, it would be nice to add get_info, delete, delete_old, and run_async.
