"Add .. to the context of the instance declaration" code action code gen doesn't work with standalone deriving declarations

[googleson78]

It adds the context before the "instance" keyword
e.g.

data Bla

deriving <adds-it-here> instance Eq Bla


deriving instance <should-be-here> Eq Bla

Funnily, right now, if there is a function below the standalone declaration, it adds the context to the function 😅
