Handle packageManager in package.json

[viraptor]

When using mise in a project with packageManager defined in package.json, I would expect that package to be installed/used in the same way .foo-version files are used.

But this:

{
  "name": "foo",
  "version": "1.2.3",
  "packageManager": "yarn@1.22.19"
}

and

mise x yarn -- yarn

ignores the configured version and runs (for example) v4.x.x

I think this could be done as a vfox/asdf/core plugin which just uses whatever node is on PATH. That wouldn't use corepack but I'm wondering if that ultimately matters to the user.

Isn't the node choice already done in the yarn plugin? I can mise x yarn@1.2.3 -- yarn install and it does the "right thing" in this case.

The only remaining issue seems to be not selecting the default version through the json file.

that would be a feature request for asdf-yarn
