🚀 Feature: Support [init] and [deploy] for Dart runtime

[cddqssc]

🔖 Feature description

I'm a fan of Dart, and I'm thrilled to see that Appwrite Functions supports the Dart runtime in the document. However, when I tried to initialize using the CLI and select the runtime, I noticed that there is no Dart runtime available. Currently, it seems that only Node.js, PHP, Python, and Ruby are supported.

🎤 Pitch

“appwrite init function” support dart runtime
