Deno `--unstable` is deprecated. Use granular flags instead.

Describe the bug
From Deno - Unstable Feature Flags:

Warning

--unstable is deprecated - use granular flags instead

The --unstable flag is no longer being used for new features, and will be removed in a future release. All unstable features that were available using this flag are now available as granular unstable flags, notably:

• --unstable-kv
• --unstable-cron
  Please use these feature flags instead moving forward.

To Reproduce
Steps to reproduce the behavior:

1. Run supabase init.
2. Input "y" for the Generate VS Code settings for Deno? [y/N] prompt.
3. Verify deno.unstable: true in .vscode/settings.json.

Expected behavior
The VS Code configuration uses granular flags for Deno.

Proposed solution
Replace the following line:

cli/internal/init/templates/.vscode/settings.json

Line 6 in 230be7f

"deno.unstable": true,

with something similar to:

 "deno.unstable": [
  "bare-node-builtins",
  "byonm",
  "sloppy-imports",
  "unsafe-proto",
  "webgpu",
  "broadcast-channel",
  "worker-options",
  "cron",
  "kv",
  "ffi",
  "fs",
  "http",
  "net"
],

This array contains all current unstable flags featured on the Deno website, and it should match the previous boolean setting.
