chore(test): set COREPACK_ENABLE_STRICT: 0 for create-next-app tests (

#56955)

I think some of the runners are missing `yarn` globally installed so its attempting to install with corepack. But the default behavior of corepack is to use the repo version (pnpm in this case) so running `yarn` will error. This PR disables corepack strict mode to avoid that problem.
