Restore Pythnet RPC page with updated content

- Restore pythnet-rpc.mdx page with providers list
- Update intro to not tie exclusively to Hermes self-hosting
- Remove paragraph about self-hosting Pythnet RPC
- Re-add pythnet-rpc to navigation and api-instances-and-providers.mdx

This addresses feedback that the Pythnet RPC page is still needed
for other workflows beyond Hermes self-hosting.
