Update package.json for expo@51.0.0 dependency

[winstromming]

What do these changes do?

Updates an expo core package dependency.

Why are these changes necessary?

Because @expo/config-plugins@7.2.5 throws an error during the expo-doctor stage and @expo/config-plugins@8.0.4 is the latest compatible version.

✔ Check Expo config for common issues
✔ Check package.json for common issues
✔ Check native tooling versions
✔ Check dependencies for packages that should not be installed directly
✔ Check for common project setup issues
✔ Check for issues with metro config
✔ Check npm/ yarn versions
✔ Check Expo config (app.json/ app.config.js) schema
✖ Check that packages match versions required by installed Expo SDK
✔ Check for legacy global CLI installed locally
✔ Check that native modules do not use incompatible support packages
✔ Check that native modules use compatible support package versions for installed Expo SDK

Detailed check results:

Expected package @expo/config-plugins@~8.0.0
Found invalid:
  @expo/config-plugins@7.2.5
