docs(turborepo): Update managing dependency for yarn berry (#8637)

### Description

I noticed that the documentation mentions Yarn 2+, but doesn't explain
the correct way to install dependencies when using that package manager.
It's well documented
[here](https://yarnpkg.com/cli/workspaces/foreach#usage), so I went
ahead and updated the documentation to reflect the correct approach.
