Support for dprint installed locally with yarn

[MariaSolOs]

Currently there seems to be the workaround of "dprint.path" to indicate the path inside local node_modules. But given that modern Yarn doesn't have a node_modules folder, how could one fix this?

For reference, this page mentions how the editor SDK hooks up with Prettier. It would be great to have something like this with dprint :)

I wonder if the extension should check for a package.json and if there's an entry in there for dprint and no node_modules folder, then it will check yarn's cache for a dprint package that matches the version requirement.

I don't understand the documentation on that page unfortunately.

Actually, maybe #38 would solve this? Or maybe the extension could try running yarn bin dprint to figure out the path.

@dsherret yes I think that would work!
