Now `Zed` can display icons. The image below shows the icon of the
`zed.exe` file and the icon in the right-click properties.

I used the `crates\zed\resources\app-icon@2x.png` file to generate the
`.ico` file. Due to some blank space around the logo in the original
file, the logo appears slightly smaller on Windows compared to other
software.

The current `.ico` file contains logo files of multiple sizes: 16x16,
24x24, 32x32, 48x48, 64x64, 96x96, 128x128, 256x256, 512x512.
