[WIP] (docs) make landing MCP doc root more actionable

[ronan-apollo]

Opening this as a local branch PR to replace #402 (fork based).

This PR modifies the MCP docs homepage, to try and replicate the card-type structure seen on Router and other Docs landing pages.

• uses card layout to highlight main actions / features
• moves 'what is mcp' / 'what is apollo mcp' to a new sub page called 'how it works'

Note: I'm not 100% on whether the card-layout works in these MDX centeric parts of the Docs structure, the templating here may be more restrictive (seems like those pages are Astro based landing pages in docs-rewrite) but I want to get a deploy preview up to test what's possible with the formatting here.
