python-click 8.3.0 breaks apkg build-dep [--list] behavior

Click 8.3.0 changed behavior of --default / --flag_value in a backward incompatible way.

apkg build-dep now defaults to --list on click == 8.3.0 even though it defaulted to install on click < 8.3.0.

Let me note, that this is a ridiculous change for a minor release of a core library to do - it literally makes my tool do THE OPPOSITE of what it did before without any code changes.
