Describe the bug

This bug affects yarn only. I have tested with NPM with everything else being the same and it works fine.

Validations

• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.
• The provided reproduction is a minimal reproducible example of the bug.

Reproduce the issue with npx wxt@latest init, selecting React and Yarn, then run yarn install in the generated directory. Start from the postinstall error showing that @wxt-dev/module-react cannot be found and compare the generated initialization with an npm-based setup. Done means a fresh Yarn initialization installs successfully without the missing-package error.
