--update-docblocks lowercases object name in array

I got a return value of `array<int, namevalue>` instead of `array<int, NameValue>` after running psalm --update-docblocks on https://github.com/vimeo/omnipay-vindicia/blob/80dbd70973c6beadb6d09d46d232964ac4c06e57/src/Message/HOAAuthorizeRequest.php#L112
