Support `-components` as `components` etc.

I'm developing a frontend project using TanStack Router.

Using TanStack Router file-based routing, I want to make -components directories, -apis directories, -hooks directories, etc.
However, Material Icon Theme shows the ordinary directory icon.

You can personalize it in settings.json

  "settings": {
    "material-icon-theme.folders.associations": {
            ".tanstack": "Core",
            "_index": "Home",
            "-index": "Home",
            "index": "Home",
            "-components": "Components",
            "_components": "Components"
      }
}
