Update the app icon for macOS to match design guidelines

Fully recognize this is in no way critical, but would be a nice (hopefully minor) improvement.

What problem do you see this solving?
The app icon for Capture One on macOS doesn't follow the "rounded square" design convention of app icons that was rolled out with Big Sur. The iPadOS/iOS icons already follow the convention for those platforms. 

When was the last time you were affected by this lack of functionality, or specific tool?
I mean, I see this daily, but again, I'm not deeply affected by it.

Are you using any workarounds or other solutions to achieve your goals in Capture One?
Nope.

Are you happy to be contacted further about this suggestion or request?
Sure.
