Document that Length parameter needs Julia 1.7 (#45961)

* Document that `L`ength parameter needs Julia 1.7 vtjnash added the 4th type parameter `L` in #41619 to `StepRangeLen`. That addition seems to have appeared in Julia 1.7 so it should be documented as such. I found this out the hard way because my CI for code that used `L` is failing with Julia 1.6.
