Migrate to turbo and pnpm

[onnimonni]

We are using such an old version of Lerna that just building this package from the master branch is getting very tough.

I based this PR on top of: NotionX#461.

When running turbo build I did get an error from one of the examples and thus needed to install the prismjs to the full example:

notion-x-example-full:build: Failed to compile.
