feat!: remove Go and Rust function templates

[serhalp]

Summary

BREAKING: Remove Go and Rust templates from netlify functions:create command.

These are rarely used and not worth maintaining here.

Go and Rust functions are still supported; this only removes templates from the CLI.

📝 Walkthrough

Summary by CodeRabbit

• Breaking Changes
  • Removed Go and Rust serverless function template support. Only JavaScript and TypeScript runtimes are now available for creating functions.
  • Removed associated build guidance and configuration messages related to unsupported runtimes.

Walkthrough

This PR removes Go and Rust function template support from the codebase. The changes delete the complete hello-world function templates for both Go and Rust, including their metadata files (.netlify-function-template.mjs), build manifests (go.mod, Cargo.toml), and implementation files (main.go, src/main.rs). Additionally, the function creation command is updated to remove Go and Rust from the list of available languages and to remove related environment documentation.

183-187: Redundant ternary — edge-function language filter is now a no-op.

With languages reduced to only [javascript, typescript], the funcType === 'edge' guard that filters out Go/Rust values is no longer needed; both branches of the ternary now produce identical arrays.

♻️ Suggested simplification

-    const langs =
-      funcType === 'edge'
-        ? languages.filter((lang) => lang.value === 'javascript' || lang.value === 'typescript')
-        : languages.filter(Boolean)
+    const langs = languages

In `@src/commands/functions/functions-create.ts` around lines 183 - 187, The
ternary used when computing langs is redundant because languages now only
contains javascript and typescript; simplify the assignment by removing the
funcType === 'edge' branch and set langs to the common value (e.g., use
languages or languages.filter(Boolean)) where the variables language, langs,
funcType, and languages are referenced in functions-create.ts so the
edge-specific filter is eliminated.
