[Feat] Expose the whole Node object to to renderFn instances

[Edo-San]

The purpose of this PR is to provide an initial solution to the issue reported on #129
If we let users get the whole Node object inside schema resolver functions, they will be able to use that data (map pieces of content to specific props, use as conditional logic, etc.).

FYI @edvinasjurele This is a simple PoC that should at least provide the very basic functionality needed to handle any custom case. No frills 😅

WDYT?
If that's fine I can add some lines to the README file. Maybe should we get rid of the existing Codeblock so that we can showcase the native Astro Code component as the main use case for this update?

Thank you in advance! 🙏

Hi, @Edo-San, thanks, for looking into the code.

Hi, made solution on my MR #168. I hope that one will be a good candidate to merge. Wanted to try the descturcture ({ attrs }) possibility and not (node) + node.attrs, thus made TS a little differently.

Closing due to #168
