Title:
(feat) Add Option to Select Programming Language (Kotlin or Java) for Android Plugins

Description:
This pull request introduces the ability to select the programming language (Kotlin or Java) when working with Android plugins.

Key Changes:

1. Kotlin Templates:

   • Added templates for Kotlin as an alternative to the existing Java templates.
   • Developers can now choose Kotlin during plugin creation, providing greater flexibility and allowing the use of Kotlin's modern features.

2. Dependency Management:

   • When Kotlin is selected, the necessary dependencies for Kotlin support are automatically added to the build.gradle file.
   • This ensures the generated project is correctly configured for Kotlin development without manual intervention.

3. Enhanced Development Workflow:

   • This new feature streamlines the development of plugins by providing an easy choice between Java and Kotlin, based on developer preference or project requirements.

---

Changelog:

• Added: Kotlin templates for Android plugin development.
• Updated: Build configuration (build.gradle) to include Kotlin dependencies when Kotlin is selected.
• Enhanced: Plugin creation workflow to allow selecting between Java and Kotlin.

---

Notes:

• Ensure to test the new workflow with both Kotlin and Java templates to verify correctness and compatibility.
• The Kotlin dependencies added to build.gradle include standard configurations required for compatibility with Android projects.

Hey @fabiomartino, thanks for the PR! Apologies for the time it took to take a look at it. I did some minor fixes and improvements that I noticed but overall it looks good, tested here and it's all working fine.

For reference: Most of the tests I did are available at https://github.com/OS-pedrogustavobilro/test-create-capacitor-plugin-pr122

Hi @OS-pedrogustavobilro, thank you for the review and for the feedback!
I'm glad to see this moving forward.

I've also opened a related proposal here (#141) which I think could be a valuable addition to the project.
Feel free to take a look when you have a moment, as it might complement these changes well.

Looking forward to your thoughts!

@fabiomartino merging this PR. As for #141, from a quick look I gave it makes sense, but we'll take a closer look and provide feedback there. Thanks again!
