The Renovate config in this repository needs migrating. Typically this is because one or more configuration options you are using have been renamed.
You don't need to merge this MR right away, because Renovate will continue to migrate these fields internally each time it runs. But later some of these fields may be fully deprecated and the migrations removed. So it's a good idea to merge this migration MR soon.
