Replace Yarn v1 #11089
Description
Problem Statement
Yarn v1 hasn't been supported for a long time and no longer gets bug fixes. At this point it's passed its best and struggles to resolve dependencies where newer options do not!
Solution Brainstorm
Maybe use Yarn v4?
The main blocker seems to be that Yarn v4 is only distributed via corepack and Volta isn't compatible as it doesn't expose the corepack binary.

If it is any help, we replaced Yarn1 with regular npm 10 and the transition was near seamless.
