Fixes FunkinCrew/Funkin#3545

Description

This commit made it so that burpSmile and burpSmileLong would set playerVolume to 1 so that Pico's burps would always be heard.

This PR adds burpShit to the list of animations, ensuring that Pico can burp to his heart's content.

South (Pico Mix) in 0.5.1

I don't know if HScript supports it but all those checks could probably be simplified into a if (name.startsWith("burp"))
Edit: It does support it but not as an extension for String, so StringTools.startsWith would need to be used instead.

But good PR 👍
