Feature Request: corepack info

Feature Request: corepack info

Running corepack info should result in a listing describing what corepack knows about the local directory and how discovered, and then the same information about the global environment

contrived example (created in a pre-caffeinated environment)

$ corepack info

corepack report:
   node version: 16.8.0, npm version: 7.21.0
   local package manager [via package.json]: yarn@3.2.0
   global package manager [via ~/.yarnrc]: yarn@3.2.0
   available package managers: yarn@1.22.19, yarn@3.2.0
   install directory: /usr/local/bin/corepack 

Why?

I've got the package managers lined up and working as described - but when I run docker-compose build I get yarn@1.22.19 -- and I can't figure out why...

Note:

I don't understand exactly, but that's not the install directory... it's what which corepack returns - but the real install directory is here: /usr/local/Cellar/corepack/0.14.0/libexec/lib/node_modules/corepack (installed via brew on a Mac)

I'm trying to disable yarn@1.22.19 but I can't, I think I can only disable yarn and then reactivate yarn@3.2.0

The issue names no files, tests, or entry points, so first locate the corepack CLI handling for local and global package-manager discovery. Done means corepack info reports the requested Node and package-manager details, explains how each was discovered, and distinguishes available versions and installation information.
