MDL-64906 disabledIf -> hideIf made the Quiz settings form more confusing. Should be reverted

MDL-64906 did a global search/replace disabledIf -> hideIf in the mod folder in Moodle, without consulting component owners.

In the case of the quiz, this turns finding the quiz setting you want into a mystery meat treasure hunt.

The way it was before, you could see all the settings that existed, even if, because of the various bits of dependency logic, they were not currently applicable to this quiz. Then, if you wanted to use that feature, you had the right words to search the docs and find hot how to use it.

I only discovered MDL-64906 when I was helping a confused user in the Quiz forum, and did git blame on the form code to work out when and why disabledIf was changed to hideIf. I think this change needs to be reverted.
