refactor(ingredients): rename options
We have options that it'd be nice to bring under our ingredient names to
disambiguate them... the option for "niri.niri.<foo>" is a little weird
but it's better than calling it "niri.<foo>" and having a base either
"development.<foo>" or "jujutsu.<foo>" for the jujutsu options.
This is subject to change in future - for example we might decide that
if the filename and ingredient name are the same we should use it only
once - however options are not commonly added to ingredients so that
would create potential naming conflicts for little benefit so we may
well not decide to do that too...
