fix(api): nvim_create_user_command addr option should allow ranges #35077

Problem: Using `addr` without `range` in nvim_create_user_command gives
"No range allowed" error, inconsistent with `:command -addr` behavior.

Solution: Set EX_RANGE flag when `addr` option is specified to match
`:command` behavior.
