Sushi Action Providers, typescript fixes

- [x] - Sushi Actions (swap, quote, find-token) #309
- [x] - ViemWalletProvider type fixes (and more!) #311
- [?] - Misc documentation improvements

### Docs
I couldn't find the repo for the documentation, so here's a couple misc bullet points:

#### [AgentKit Docs](https://docs.cdp.coinbase.com/agentkit/docs/welcome)
Sidebar -> Api Docs -> AgentKit (Typescript) is a 404
Sidebar -> Support -> Community Guides is 404
Sidebar -> Support -> FAQ 404

#### [AgentKit Docs -> Quickstart](https://docs.cdp.coinbase.com/agentkit/docs/quickstart#step-3-run-the-agent-1)
Step 3, typescript version. `examples/chatbot` doesn't exist. The actual path is `typescript/examples/langchain-cdp-chatbot`

#### Suggestion
Add a quick tutorial for `npm link`ing the `agentkit` package to one of the examples for testing.
