Fallback to global or bundled remark version

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and couldn’t find anything (or linked relevant results below)

Problem

A user wishes to use unified-language-server or remark-language-server without installing remark in their local project folder

Solution

unified-language-server should fall back to a global or bundled installation of remark if a local one is not found

Alternatives

installing remark locally solely for the sake of a specific class of editors is not ideal

This project allows that. Pass defaultProcessor.

Yes, this project allows that, but remark-language-server doesn’t use it.

I’m curious to the scenario. Why does this user wish to use remark-language-server without installing remark in their local project folder?

I could imagine a number of scenarios, e.g.: Does the project use remark or remark-cli? Does the user want to use remark-language-server, but doesn’t the project use remark? Does the project use pnpm?

Here's one scenario, which I imagine is probably very common:

• The repo contains markdown files
• The repo does not use remark in any of it's app code or dependencies
• The user wants to format markdown files in the repo
• The user does not want to install any extra dependencies

At the moment, neovim users who follow the docs all the way down the rabbit hole, and end up installing the remark server, are going to get this error notification on every. single. character. they. type. in. a. markdown. file.
