Priorities other than A,B,C

I use priorities below C *constantly* and for *everything*, and have just spent way too long being confused about whether I'm using org-ql wrongly, before finally finding a temporary workaround. It'd be really nice to update, or if nothing else change the docs to state that it ignores most values.

Quote from the source:

(;; NOTE: This only accepts A, B, or C. I haven't seen
;; other priorities in the wild, so this will do for now.
