Better Steam Deck integration and full controller support!

We have improved Strange Horticulture's Steam Deck integration - everything should now work out of the gate with no need to fiddle around with any extra controller setup (just make sure you're using the recommended controller layout which should be selected by default).

We've also added full controller support to the game so you can now play with a gamepad if that's your jam.

We've also added a small fix for a minor Mac issue that meant that an achievement wasn't being awarded properly.

P.S. There's still a couple of days left to grab a Hellebore plushie but time is running out fast! https://shop.makeship.com/3TFRLrP
