Latest NPM versions throw an error when workspaces are configured

[aitkenster]

Describe the bug

Versions of NPM greater than 8.4 throw an error if the build is using NPM workspaces. It seems like the reason is workspaces aren't compatible with npm set so we might need to rethink this command

To Reproduce

Steps to reproduce the behavior:

1. Create a monorepo using npm workspaces.
2. Deploy to Netlify.
3. See the errors being logged.

Configuration

NPM_VERSION isn't set

Expected behavior

No error logs
