refactor(daedalus_client): replace serde-xml-rs with quick-xml (#7185)

quick-xml is already the de facto XML (de)serializer used
elsewhere in the workspace (labrinth, app-lib), so consolidate
on it here too. Its serde feature deserializes the existing
maven-metadata.xml structs without any changes. Drops one
redundant dependency from the workspace.
