feat: Upgrade kiosk_mode

[alboiuvlad29]

Summary

Upgrades kiosk_mode:

• To use the latest available AGP
• To use the latest Kotlin version
• Updates the example app to use imperative plugin apply
• Replaces deprecated .buildDir with .layout.buildDirectory.

The changes are accurate, as they're taken from a freshly created app and plugin using flutter create. This should future-proof the package and allow the migrations to higher AGP versions in client flutter apps.

Fixes:

• [Android] "Execution failed for task ':kiosk_mode:compileDebugKotlin'" ('compileDebugJavaWithJavac' (1.8)) #694
• kiosk_mode: android:attr/lStar not found when assembling in release mode #681

Testing steps

Ensure that kiosk_mode package and example app work as expected. I've tested the example app.

Let's take it a step further and finally start using a version catalog.

@Sevastyan Don't believe it's working properly with the flutter plugin. See this diff.

For some reason it's expecting the same libraries declarations in the example app which are declared in the plugin's catalogue, while it shouldn't. It also doesn't work with settings.gradle as the evaluation happens after this file.

[Sevastyan]

Let's not this stop the PR from being merged.

However, keep in mind that version catalog is the standard we should migrate to sometime.
