Feature Request - yarn outdated - ability to group/sort by workspace

[jharris4]

In a monorepo using yarn workspaces, the result of running yarn outdated looks like this:

yarn outdated v1.22.4

It would be REALLY nice to have some way to also sort this output by the Workspace column as well as just the Package column.

This could just be an extension of the existing PR 2759

It might be a good idea to add a CLI argument to enable such a feature, maybe something like yarn outdated --group-workspace
