Ignore Heroicons in VS Code

Phoenix 1.7 changed the way Heroicons are included in your project. 1.7 now vendors the SVG files in assets/vendor/heroicons. Visual Studio Code will index these files for search by default, polluting your search results and the Go To File (⌘ + P) functionality.

A very simple way to prevent this is to create a custom per-project search exclude. In .vscode/settings.json (create if it does not exist) add the following setting:

{
  "search.exclude": {
    "**/heroicons": true
  }
}

Heroicons will now be excluded from all search or "go to" operations.
