[web] introduce temp onClickDisconnectKeyserver
Summary:
As of Nov 2023, disconnecting from a keyserver is outside the scope of the keyserver selection screen. However, we currently have the UI for this already implemented so as a temporary solution this diff has the onClickDisconnectKeyserver callback display an alert to the user, informing them that this feature is not quite ready yet
Depends on D10079
Test Plan:
Please see the demo video below
