Don't check for keyboard appearing on catalyst (#21)

# Don't check for keyboard appearing on catalyst

## ♻️ Current situation & Problem
For our text entry implementation, we currently maintain a special check
for `macOS` to not check for keyboard existence (as there is no UI
keyboard don macOS). This check currently isn't used on the catalyst
platform. This PR fixes that for macOS Catalyst as well.


## ⚙️ Release Notes
