Add "Audio" as a Step Type

We're introducing "Audio" as a new Step Type to support workflows that involve voice interactions, recordings, or AI-generated audio processes.

Why This Matters:

✔ Expands step types to include audio-based interactions, similar to Video.

✔ Supports AI agents or automation tools that rely on voice processing or audio output.

✔ Enables better workflow documentation for steps that involve calls, voice recordings, or audio-driven actions.

With this update, users can seamlessly integrate audio-based workflows into their process mapping, keeping Puzzle adaptable to evolving automation needs. 🚀
