New Feature: Prosemirror Meta Package

[bdbch]

Changes

This PR introduces a new @tiptap/pm package which includes all necessary prosemirror modules as a meta package that should resolve the dependencies of Tiptap.

This should resolve issues like #3529 #3497

Right now this PR waits for #3555 since this requires changes to our build process which need to be tested first.

This will allow access to prosemirror packages like this:

import { EditorState } from '@tiptap/pm/state'
import * as Tables from '@tiptap/pm/tables'

---

Open Todo

• Update documentation @bdbch
• Update installation guides @bdbch
• Add upgrade guides @bdbch

@bdbch It seems that starter-kit still needs to updated.
I tried importing the following extensions from starter-kit@2.0.0-beta.212 and I get the following errors:

@tiptap/starter-kit doesn't provide @tiptap/pm, requested by @tiptap/core
@tiptap/starter-kit doesn't provide @tiptap/pm, requested by @tiptap/extension-code-block
@tiptap/starter-kit doesn't provide @tiptap/pm, requested by @tiptap/extension-dropcursor
