The code action to add missing language extension adds it in the wrong place

[jhrcek]

The current behavior of this code action is problematic.
It seems to be adding the LANGUAGE pragma below the last pragma in the file.
If you happen to have some pragma like INLINE somewhere below, the LANGUAGE pragma is added after that.
But LANGUAGE pragmas are only valid before the module declaration.
See this gif illustrating the issue:

Steps to reproduce

Create a haskell file like this, hover over the one and select code action Add "TupleSections"

{-# LANGUAGE NamedFieldPuns #-}
{-# LANGUAGE QuasiQuotes    #-}

module PI.Db.Code.Project where

tupleSection = (1,) <$> Just 2

{-# INLINE addOne #-}
addOne x = x + 1

Expected behaviour

Missing language pragma is added before the module declaration, where it is valid.

Actual behaviour

Missing language pragma is added after the last pragma in the file.

thanks for reporting the issue, we already have it in #1958 though
