Bump Tiptap packages to minimum of beta.210 with tiptap/pm package

When switching any tiptap package to the beta.210+, we have to use
`@tiptap/pm` for all prosemirror stuff exclusively, in order to ensure
we have consistent prosemirror package  versioning, as described in
https://tiptap.dev/blog/new-pm-package-and-upgrade-guide-for-beta-210

And as such this bumps all packages to beta.210+, most notably to get
around quirks with the prosemirror-tables extension as described in
#45
