This commit introduces a collection of code snippets demonstrating the usage of the Gemini Developer API. It includes examples for model configuration, text-only and multimodal inputs (image, audio, video), multi-turn chat, and image generation/editing. The necessary dependencies for Firebase AI, Guava, and Reactive Streams have been added to gradle/libs.versions.toml and misc/build.gradle.kts.

This commit adds new Kotlin snippets for the Firebase AI Imagen API. The snippets demonstrate how to: - Configure the Imagen model with options like image count, aspect ratio, and safety settings. - Generate an image from a text prompt. Region-Tags: - `android_imagen_model_configuration` - `android_imagen_generate_images`
This commit introduces snippets for Imagen 4.0, a text-to-image generation model. It adds new files, `ImagenSnippets.kt` and `ImagenSnippetsJava.java`, which demonstrate how to configure the model and generate images from a text prompt.
The commit also includes the following changes:
- Adds the `@PublicPreviewAPI` annotation to the new Imagen snippets.
- Refactors existing Gemini snippets to initialize models within a static block for consistency.
- Adds `@SuppressWarnings("unused")` to several functions and classes to handle linter warnings.
- Updates the `build.gradle.kts` file to exclude the `.idea` directory from Spotless XML formatting.

Is there a way to use dev site variables in our snippets?
I want us to try to move away from hardcoding the model names in our DAC code blocks.

Same question. :) Further to this point, we're sharing values with other teams. Can we just add those variables in here or will that cause questionable results?

The documentation does not currently use variables. If you want to turn those into variables, we could make a separate standalone hard-coded snippet in the documentation that uses the documentation tool variables, but we cannot use the same variables in GitHub. We could then modify the GitHub code to use the same variable name, and define the variable somewhere outside of the snippet region tags.

@sanbeiji do you have any additional feedback on this? Since there aren't any equivalent documentation variables to consider right now, perhaps we can address that later if those variables are created?
