Need to sort out typings issues when updating all core dependencies

[JulianCataldo]

After doing a nuclear pnpm up --latest:

It works well with no regressions during runtime.
But sadly a lot of typings broke into havoc for major semver bumps.
I still have to wrap my head around various API changes for unified and friends deps. before publishing an update for this plugin, with 100% correct internal types.

I can't focus on this right now, but it's in my scope. As for now, this plugin is doing its duty, even with latest the remark versions.
In the meantime, any help will be appreciated!
