Closes#34976
## Root Cause
The current implementation of `fmt::Display` in
`KeyBindingContextPredicate` hardcodes a parentheses around `And` and
`Or` cases. Causing the text displayed on the keymap editor to have
nested parentheses.
This PR refactors the display logic and make the parentheses added only
when there's nested operator.
