Make AdGuard (Autoupdate) icon a rounded-rectangle to match Big Sur style guide

[rakleed]

Issue Details

The current AdGuard icon (Autoupdate) doesn't match modern macOS style guides, so it doesn't look good against the background of other icons.

Proposed solution

Could you please update the AdGuard (Autoupdate) icon for macOS according to Big Sur specifications?
