Clean up AndroidManifest.xml by removing redundant package declaration

[Muhammed-Ayad]

This PR removes the deprecated package attribute from AndroidManifest.xml. Starting with Android Gradle Plugin 7.0.0, the package attribute in the manifest has been deprecated in favor of the namespace property in build.gradle.

Changes made:

• Removed the package="com.crazecoder.openfile" attribute from the manifest

Benefits:

• Aligns with modern Android development practices
• Reduces potential conflicts between manifest package and Gradle namespace
