Include a controller or joystick as part of the default icon set

[MechMK1]

Summary

Many people use KeepassXC to keep track of credentials for various games, often in the form of a dedicated group. Unfortunately, the default icon set does not include any icons that would be suitable for this role.
Therefore, I propose to include either the game controller icon, or the joystick icon from icons8, as they allow free use for open-source projects (and several of the existing icons are from icons8 already).

Examples

Specifically, I would suggest either this icon:

Or this icon:

While a minor request, I believe this would add to the user experience as a whole.

For now just add those as custom icons and use it for your entries. We are looking into ways to expand the default icon set but unfortunately it is bounded by the kdbx standards that keepass sets.
