Use semantically correct element for closed captions element

[Neo-Oli]

Hi

The closed caption element should probably be a <span>. I want our cc element to be a <p> since that makes semantically the most sense for us (but I could see people deciding on something else). <div> will get rendered inside our <p> now, but <div> inside <p> (or most other text elements) is semantically invalid.

const divElement = document.createElement("div");

I implemented chart(js)2music now and noticed a few bugs. So that's why I am creating several issues, but overall I'm quite happy with the plugin. ❤️
