✨ Icons for every file format and file format opacity

### Is your feature request related to a problem? Please describe.

### Describe the solution you'd like

CodeEdit does not have `SF Symbols` icons for every language (including those it doesn't have syntax highlighting).

Some filenames do not have their proper extensions because it would take too much time to research them.

### Additional context

The `SF Symbols` library has a lot of icons that we could use for the languages.
At some point I'm going to submit a PR from this fork: https://github.com/iggy890/CodeEdit/tree/file-icons
