4.0.1 — R8 fix for release builds

Patch release covering two issues uncovered while testing 4.0.0 against
a real consumer's R8-minified release build, plus translations for the
new autocomplete strings shipped in 4.0.0. No public API changes —
drop-in upgrade from 4.0.0.

🐛 Fixes

• Release build crashed on Places.createClient with
  NoSuchMethodException / ServiceConfigurationError. Root cause:
  the Places SDK 5.x reflectively instantiates its internal classes
  via two paths — protobuf reflection (on proto messages that extend
  zzbdq) and JDK ServiceLoader (for gRPC name resolvers and
  similar SPI providers). The SDK's shipped proguard.txt only keeps
  the proto subclass fields, so R8 strips the constructors and the
  consumer's release build fails on startup. PING now ships a consumer
  proguard rule that keeps every constructor of every internal Places
  SDK class. Consumers get the fix automatically.

🌍 i18n

• Translate the two new picker_autocomplete_* strings (search hint
  and close-button content description) added in 4.0.0 into all 9
  supported locales: ar, ca, cs, de, es-rES, ko-rKR, pt, tr, zh-rTW.

🧹 Internal cleanup

• Drop the now-unused kotlin-parcelize plugin (last user was
  CustomPlace, removed in 4.0.0). With parcelize gone, also drop the
  explicit kotlin-android plugin and the android.builtInKotlin /
  android.newDsl opt-outs in gradle.properties — we're now on
  AGP 9's built-in Kotlin support with no opt-outs.

📦 Install

dependencies {
    implementation("com.google.android.libraries.places:places:5.1.1")
    implementation("com.github.rtchagas:pingplacepicker:4.0.1")
}

Anyone on 4.0.0 with minifyEnabled = true should upgrade — release
builds will crash on startup without this patch.
