./gradlew migrateToSplitties

[jmfayard]

Not a blocker for now, but for the 3.0 release, we should expand the feature that was developed for ./gradlew migrateToAndroidX

## Your turn: add the AndroidX libraries to app/build.gradle

// app/build.gradle
dependencies {
    implementation(AndroidX.legacy.supportV4)
    implementation(AndroidX.legacy.supportV13)
    implementation(AndroidX.cardView)
    implementation(AndroidX.appCompat)
}

Code: https://github.com/LouisCAD/Splitties/blob/ffe99caf761e817453309deddf0f5958ae628f1f/plugin/src/main/kotlin/com/louiscad/splitties/MigrateAndroidxTask.kt#L88-L94

What would need to change:

• find a good name for the new task (hard)
• have one task by project, instead of one task globally like migrateToAndroidX
• consider all dependencies present in Splitties and not only AndroidX
• use the right configuration name. Currently it's hacked together to use either implementation or androidTestImplementation.
