chore: update to Expo 51 and Cocoapods 1.15.2

[D4ryl00]

This PR updates dSocial to the latest version of:

• GnoNative (with Expo 51)
• Expo 51
• Cocoapods 1.15.2

Expo 51 uses React Native 0.74 which uses Java 17 (see here): If you have already installed JDK on your system, we recommend JDK 17. You may encounter problems using higher JDK versions.

The previous version used was Java 18 which created a conflict between the two versions: Inconsistent JVM-target compatibility detected for tasks 'compileDebugJavaWithJavac' (17) and 'compileDebugKotlin' (18).

Finally, this PR also removes the native folders and adds them in the .gitignore files because they are automatically created npx expo run:ios (or android), following the recommendations of npx expo-doctor@latest.
