lit v2

[bennypowers]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch @morbidick/[email protected] for the project I'm working on.

this patch updates the type definitions to use lit v2.

NB: the patch also updates the runtime code to use the ReactiveElement interface NB: this patch updates the imports in sync.js but does not update the directive definition

Here is the diff that solved my problem:
