chore: Upgrade AGP 8.3 -> 8.4

[volodymyr-chekyrta]

Gradle was updated from 8.4 to 8.6, and the Android Gradle plugin was updated from 8.3 to 8.4 according to the AS Jellyfish release.

Note: java.lang.OutOfMemoryError still appears on rebuild. Workaround: change locally org.gradle.jvmargs=-Xmx2048m to a required value.
