Docs: the `dis` module does not document the `show_jit` parameter

[iamsharduld]

show_jit was added to dis.dis(), dis.distb(), dis.disassemble(), dis.get_instructions() and the dis.Bytecode class (gh-150478, Python 3.16), but Doc/library/dis.rst never documents it — even though its sibling options (show_caches, show_offsets, show_positions) are all documented.

(There is also a small typo in the documented distb signature: show_offset should be show_offsets.)
