[DOCS]: Get the Lit Docs To Be On Par With The React Documentation

[tobySolutions]

This issue was brought about after a careful observation by Corbin and is targetted to help the Lit devs community to be able to get a very useful and well detailed documentation that helps them in every way possible with their integrations of Tanstack forms in their projects and also to help with general core engineering information as to how the library works with Lit.

For reference:

• Tanstack Forms Current React Docs
• Tanstack Forms Current Lit Docs
