I've removed the NodeList example because it's confusing. Only the first element of a NodeList will be used and this is usually not what you want. I've instead replaced it with a `querySelector` and map example. It's related to: https://github.com/sampotts/plyr/issues/801
I know that there was a note, pointing out that the first element will be used, but be honest: Everybody is just scanning the examples for code and doing copy paste :D
