fix(api): add missing nargs field to user command Lua callbacks #34210

Browse Source 
Problem: nvim_create_user_command() Lua callbacks were missing the documented nargs field in the options table passed to the callback function.

Solution: Add nargs field derivation from command argument type flags in nlua_do_ucmd(), using the same logic as nvim_parse_cmd().
