Steps To Reproduce

1. In Ubuntu under WSL2 on Windows 11 (or likely any other supported build environment, I would imagine).
2. cargo generate cloudflare/workers-rs -- select templates/hello-world-http (or likely any other template).
3. cd into the new directory.
4. npx wrangler dev -- update to 3.108.0, if prompted.
