firebase deps versions are not pinned

[emanuelb]

The firebase dependencies firebase-crashlytics-ktx and firebase-crashlytics-ndk don't use a static version like in dependency firebase-bom:30.0.1 and other deps in ./configs/dependencies.gradle

nunchuk-android/configs/dependencies.gradle

Lines 112 to 113 in 11da98b

	firebaseCrashlytics : "com.google.firebase:firebase-crashlytics-ktx",
	firebaseNdkCrashlytics: "com.google.firebase:firebase-crashlytics-ndk",

Because this dependencies versions are not pinned: (fix is to add :versionNumber to them like its done for other dependencies in this file such as firebase-bom)

comparing built apk to apk from googleplay may result in diff in libcrashlytics*.so files in case by the time of local build there will be newer releases then the one used in upstream build
