fix: prevent yarn 2+ error in assets:precompile

[pftg]

Description 📖

For Yarn 2+, YARN_PRODUCTION=false causes Usage Error: Unrecognized or legacy configuration settings found: production - run "yarn config -v" to see the list of settings supported in Yarn (in <environment>)

Background 📜

Because there is no such global configuration for Yarn 2+, at least I have not found any similar on https://yarnpkg.com/configuration/yarnrc, we got the issue

The Fix 🔨

Do not add env to prevent warning message if yarn version is more than 1

@ElMassimo could you check?

It's been 3 days Paul, don't be pushy 😄

I'll check when I have time to review it.

[ElMassimo]

Yarn's migration guide mentions that selecting which dependencies are installed (dev or prod) requires the workspace-tools plugin.

Since a user might not have workspace enabled in the project, I think that the change in this pull request makes sense.

This also means it's now the user's responsibility to ensure any build dependencies are available when vite build is run.

Thanks for your contribution Paul! 😃
