This means "what" in the compound word 什么, which is the usual way to say, "what". It means "various" when it is pronounced shi2, but that form is very rarely used. It looks like someone has decided to edit this to the modern meaning, which is fine, but they should certainly leave a comment telling people why this has changed, and also the other meaning should be added as an alternative so that it isn't marked as incorrect. I certainly found knowing its ancient meaning to be useful in understanding why it was used in the compound word for "what".
So we can either leave it now as the common meaning or change it back to the original meaning - but either way edits should always be noted in the comments section.
