fix(extensions): resolve transitive `@mui/system` dependency on `@mui/x-*` packages

[LukasTy]

What's the problem this PR addresses?

Related issue: https://github.com/mui/mui-x/issues/15267

All @mui/x-* packages depend on @mui/material, which directly depends on @mui/system. The @mui/system package has a singleton. Hence, it is listed as a peer dependency on the @mui/x-* packages.

How did you fix it?

I'm proposing to add these rules to the yarnpkg extensions because Yarn PnP fails to resolve this transitive dependency.

Could someone restart the failed GH Action? Looks like a flaky error. 🤔
