Subject: [PATCH] - sx:negated from ShExR

The ShEx 2.0 draft `!` operator on TripleConstraint, removed from the language
in Nov 2016 (shexTest 224c610, spec d3f882d) over shexSpec/shex#11 and replaced
by {0,0} and ShapeNot. fe51e15 copied it back into ShExR from ShExJ.jsg seven
weeks later; e01f012 cleaned the grammar in 2020 but not ShExR. It was never in
http://www.w3.org/ns/shex#, is not in the spec, and the ShExC parser has no `!`
rule, so nothing could produce it. Matches shexTest 265f62f.
