Add "actually..." (☝️🤓) emoji cow

Nice to see the project being maintained. I made this cow a few days ago, I even shared it on the Fediverse: https://lemm.ee/post/39579433 It's based on the _popular_ "erm actually" ☝️🤓 emoji combo, someone may like it so here we are. I was thinking maybe it's better to rename the file to `actually.cow`, the bad ortography comes from a meme, maybe not so relevant here, what do you think?
