Silence avoid-c-arrays on put_literal's array reference

clang-tidy flags the reference-to-array parameter under
cppcoreguidelines/hicpp/modernize-avoid-c-arrays, and the CI treats warnings as
errors. Binding to the array is the whole point here - it is what lets the
length be deduced from the literal instead of hand-written at the call site - so
suppress it the same way from_json(), to_json() and get_to() already suppress it
for their own T (&arr)[N] parameters.
