`universal` keybindings should be overridden by keybindings of other categories

**Is your feature request related to a problem? Please describe.**
I want to set `keybinding.universal.copyToClipboard` to `c`, however it disables any other keybindings to `"c"` like `keybinding.files.commitChanges`.

**Describe the solution you'd like**
Keybindings in `universal` category should not override that of any other categories including `files`.
