(update): big rewrite and design of docs

[ErikKaum]

High level goals we're trying to achieve with this:

• Idea is to make it clear that Inference Endpoints is the central place where you deploy high performance Inference Engines (like vLLM, TGI etc.) --> de-prioritize the default container (and rename it to the inference toolkit)
• Make screen shots and docs in general up to date
• Reorganize docs to reflect the use-cases we have today
• Solid and to-the-point guides
• Informative tutorials with more in-depth dives on how to deploy popular applications/solve common problems

The docs for this PR live here. All of your documentation changes will be reflected on that endpoint. The docs are available until 30 days after the last update.

I reviewed this here

tbh, I would get this merged asap and iterate on smaller changes.

Thank you 🙌 Yeah I'd say that it's in a good state now to ship and the iterations will come for sure!
