[Infra] Replace prettier with flexmark as markdown formatter (#7593)

There were some issues running prettier, as a node package instead of
java/kotlin.

Replacing it with flexmark addresses the issue. See
https://github.com/diffplug/spotless/tree/main/plugin-gradle#freshmark
for information about flexmark + spotless

 To work with this repository, the Android SDK must be installed. Use the `sdkmanager` command-line
 tool for this purpose.
 
-1.  **Install Android SDK Command-Line Tools**:
-
-    - If not already installed, download the command-line tools from the
-      [Android Studio page](https://developer.android.com/studio#command-line-tools-only).
-    - Create a directory for the Android SDK, e.g., `android_sdk`.
-    - Unzip the downloaded package. This will create a `cmdline-tools` directory. Move this
-      directory to `android_sdk/cmdline-tools/latest`.
-    - The final structure should be `android_sdk/cmdline-tools/latest/`.
-
-2.  **Install required SDK packages**:
-
-    - Use `sdkmanager` to install the necessary platforms, build tools, and other packages. For
-      example:
-
-      ```bash
-      # List all available packages
-      sdkmanager --list
-
-      # Install platform tools and the SDK for API level 33
-      sdkmanager "platform-tools" "platforms;android-33"
-
-      # Accept all licenses
-      yes | sdkmanager --licenses
-      ```
-
-    - Refer to the specific requirements of the project to determine which packages to install.
-
-3.  **Configure for integration tests**:
-
-    - To run integration tests, a `google-services.json` file is required.
-    - Place this file in the root of the repository.
-
-4.  **Install NDK for specific projects**:
-    - Some projects, like `firebase-crashlytics-ndk`, require a specific version of the Android NDK.
-      You can install it using `sdkmanager`. For example, to install NDK version 21.4.7075529, you
-      would run `sdkmanager "ndk;21.4.7075529"`. Always refer to the project's `README.md` for the
-      exact version required.
