Add navigation folder icon. I've used a hamburger as it's the typical icon for a menu / navigation.

@PKief I believe the "navigation" folder in React Native serves the same purpose as the "routes" folder, so the icon should be consistent with the one used for "routes." Using a hamburger menu icon doesn't make sense, as it's typically associated with opening a menu inside an app, not with navigation setup in a project folder structure.

The "navigation" folder should ideally use an icon that matches "routes," such as an arrow or a symbol directly related to navigation, rather than a hamburger menu.

Additionally, I noticed that the icon added is for "folder-navigation-open" or "folder-navigation." I only want the "navigation" icon to be applied to the folder itself, not in the open state or a different variant.

All folder icons in this icon theme have open and closed states.

@PKief @lucas-labs Thank you! However, the "navigation" folder should have the exact same icon as the "routes" folder for both its open and closed states.
The hamburger menu icon is not the right choice, as it represents a UI element rather than project navigation. Since the "navigation" folder serves the same purpose as the "routes" folder, its icon should be identical. Please apply the same icon used for the "routes" folder.

@okaybeydanol I can update it. Until then you can also set this into your user settings to change the behavior:

"material-icon-theme.folders.associations": {
  "navigation": "routes"
}

I was normally using it like that, but thanks @PKief lot, it has already been fixed. I'll see if there is an update.
