Get a customized info widget to show extra information of a proposal.
This allows for customized widgets on a proposal basis, although in general
providers will have the same custom widget for all their proposals and
proposal can be ignored. The implementation of this function is optional.
If this function is not implemented, the default widget is a GtkLabel. The
return value of gtk_source_completion_proposal_get_info() is used as the
content of the GtkLabel.
Note
If implemented, gtk_source_completion_provider_update_info()
must also be implemented.
