depends: python3-launchpadlib-desktop

Replace the dependency on python3-launchpadlib with
python3-launchpadlib-desktop. This package is the same as python3-launchpadlib
except that it also includes python3-keyring, which is a requirement for
some of the desktop-centric code-paths. In the case, requestsync has a
path for logging in via a web browser which also requires python3-keyring
to be installed. This had caused a ModuleNotFoundError when
python3-launchpadlib dropped python3-keyring from Recommends to Suggests
(LP: #2049217).
