chore: update README for 5.0.0 and remove tracked .vscode folder (#1721)

- Update installation snippet to 5.0.0 and document the new modular
  artifacts (core, clustering, data, heatmaps, ui)
- Add x-release-please-version markers so release-please keeps the
  README versions in sync
- Fix source links to the new module locations and Kotlin files
- Bump minimum API level to 23 and link the v4 -> v5 migration guide
- Remove .vscode/settings.json from version control (already ignored)

 This open-source library contains utilities that are useful for a wide
 range of applications using the [Google Maps SDK for Android][maps-sdk].
 
+As of version 5.0.0, the library has been rewritten in Kotlin and split into
+focused submodules so you can depend only on what you need. If you are
+upgrading from 4.x, see the [migration guide](MIGRATION.md).

 - **Marker animation** - animates a marker from one position to another
 - **Marker clustering** — handles the display of a large number of points
 - **Marker icons** — display text on your Markers

 ## Requirements
 
-* Android API level 21+
+* Android API level 23+
 * [Sign up with Google Maps Platform]
 * A Google Maps Platform [project] with the **Maps SDK for Android** enabled
 - An [API key] associated with the project above ... follow the [API key instructions] if you're new to the process
 
 ## Installation
 
-```groovy
+```kotlin
 dependencies {
     // Utilities for Maps SDK for Android (requires Google Play Services)
     // You do not need to add a separate dependency for the Maps SDK for Android
     // since this library builds in the compatible version of the Maps SDK.
-    implementation 'com.google.maps.android:android-maps-utils:3.20.1'
+    // The aggregator artifact transitively pulls in all submodules below.
+    implementation("com.google.maps.android:android-maps-utils:5.0.0") // x-release-please-version
+}
+```
 
-    // Optionally add the Kotlin Extensions (KTX) for full Kotlin language support
-    // See latest version at https://github.com/googlemaps/android-maps-ktx
-    // implementation 'com.google.maps.android:maps-utils-ktx:<latest-version>'
+Alternatively, depend only on the submodules your app needs:
+
+```kotlin
+dependencies {
+    // Base utilities: PolyUtil, SphericalUtil, collection managers, Street View metadata
+    implementation("com.google.maps.android:android-maps-utils-core:5.0.0") // x-release-please-version

+    // Heatmaps
+    implementation("com.google.maps.android:android-maps-utils-heatmaps:5.0.0") // x-release-please-version
