chore(ai): use kotlin 2.2.0

[thatfiredev]

It seems like dpebot missed this in #2681

The reason why it didn't update the build.gradle.kts file is because that file used the kotlin(...) function instead of id(...).

I need to investigate why it didn't update the TOML as well (see #2681 (comment))

val apiKey = BuildConfig.GEMINI_API_KEY
val client = OkHttpClient()

val request = Request.Builder()
.url("https://generativelanguage.googleapis.com/v1beta/models/gemini-pro:generateContent?key=$apiKey")
.post(
RequestBody.create(
MediaType.parse("application/json"),
"""{"contents":[{"parts":[{"text":"Hello Gemini"}]}]}"""
)
)
.build()

val response = client.newCall(request).execute()
val responseBody = response.body()?.string()
Log.d("GeminiResponse", responseBody ?: "No response")
