Add bongcloud variations [WIP - Need to fix lint checks]

I added some other bongcloud variations.

• Double Bongcloud
• Lil/baby bongcloud

I was going to add the Hammerschlag Variation:

But there is an opening called the pork-chop opening (just a different name for the Hammerchlag) that is already registered on lichess. It's possible that we could change the name; But, that's debatable...

I will fix it so lint check will pass

My bad, Lil Bongcloud Attack should be on line 207, after King's Pawn Opening: Van Hooydoon Gambit and before Portuguese Opening. Sorry for requesting changes that aren't complete. 😅

It's all good... I just merged the most recent version, I'm going to check if Lil Bongcloud Attack still needs to be on line 207, after King's Pawn Opening: Van Hooydoon Gambit
