I noticed that `updateTypes: ['patch']` only matches if `separateMinorPatch` is set to true.
This comes somewhat unexpected and does not seem to be documented anywhere at the moment, as opposed to the documentation of the `patch` setting, where the docs correctly state `Only applies if separateMinorPatch is set to true`.

Maybe related to renovatebot#2818

But without reading the docs, I would expect `updateTypes: ['patch']` to always match on patch updates (e.g. 1.0.0 to 1.0.1) regardless of the `separateMinorPatch` setting (which is only set if we want separate PRs or branches for patch AND minor updates)
