Remove represented file icon from the macOS title bar

[kittaakos]

Describe the request

win.setRepresentedFilename(filename) is a macOS-only feature to show the OS-associated file icon in the window's title bar. (See #868) While holding down the ⌘ key, it's possible to list and open container folders up to the root.

Describe the current behavior

IDE2 plans to indicate whether a local or a remote sketch is opened in the title bar with an additional icon. Probably with the cloud icon. Showing double icons could be strange.

VS Code can do the same, but the title bar icon is not required. It would be great if IDE2 could keep the file representation feature (on macOS) but without the icons.
