fix: address missing assembly section for instructions with no operands (#1237)

Remove conditional check that hides Assembly section when assembly field
is empty. Now instructions like `fence.i` will properly show "Assembly::
fence.i" in the instruction appendix instead of omitting the section
entirely.
