If the plugin identified by @info implements the @extension_type,
then this function will return a new instance of this implementation,
wrapped in a new #PeasExtension instance. Otherwise, it will return %NULL.
Since libpeas 1.22, @extension_type can be an Abstract #GType
and not just an Interface #GType.
See peas_engine_create_extension() for more information.
