📡 Document nvcc CUDA 12.0/12.1 JSON_HAS_RANGES exclusion (#5258)

PR #5248 added a 5th JSON_HAS_RANGES exclusion branch to
macro_scope.hpp (nvcc CUDA 12.0.x/12.1.x, fixed in 12.2, issue #3907)
shortly after #5252 added the "Known compiler/stdlib exclusions"
list to json_has_ranges.md, so the new branch was missing from the
just-added doc section. Bring the list back to parity with the code
(5 exclusion branches, 5 documented).

If `JSON_HAS_RANGES` is `0` despite `__cpp_lib_ranges` being defined, one of the exclusions above likely applies to your toolchain.
