[Feature] Shorthands for yarn workspace(s) CLI commands

[JosXa]

• [ ] I'd be willing to implement this feature (contributing guide)
• [x] This feature is important to have in this repository; a contrib plugin wouldn't do

Describe the user story

As a dev, I'm really tired of typing out "yarn workspace @mylib/mypackage run xyz" in my monorepo so often, and am looking for a way to reduce the effort. It also makes the NPM scripts longer than they could otherwise be.

Describe the solution you'd like

Introduce shortcuts:

yarn workspace ... == yarn ws ... yarn workspaces ... == yarn wss ...

Describe the drawbacks of your solution

We might introduce some ambiguity in docs and on sites like stackoverflow where it isn't clear what the shortcuts stand for.
