feat: Add Go language support for types generation

[Bullrich]

What does this PR do?

Adds Go language support to the Appwrite CLI types generation feature.

Test Plan

• Generated Go types successfully using appwrite types --language go types
• Verified output generates proper Go structs with JSON tags

Example of files created with the feature

I ran appwrite types --language go with the following file:

    "tables": [
        {
            "$id": "function-runs",
            "$permissions": [],

Walkthrough

This change adds Go programming language support to the type generation system. It introduces a new Go language module that generates Go structs and enums from collection definitions, integrates Go detection into the language detection logic by checking for go.mod and go.sum files, and registers Go as an available language choice in the command handler.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Type mapping implementation (lib/type-generation/languages/go.js): Verify correctness of attribute-to-Go-type mappings, including handling of relationships (one-to-many, many-to-one, many-to-many), optional pointer types, and error cases for unknown types or missing collections
• Template generation logic: Ensure the Go struct and enum code generation produces valid Go syntax, particularly JSON tag formatting and const block generation for enums
• Go project detection (lib/type-generation/languages/language.js): Confirm that go.mod and go.sum file detection correctly identifies Go projects
• Integration points (lib/commands/types.js): Verify the case handler for "go" and inclusion in language choices follow the established pattern for other languages
