rename from date format to format date (#9902)
# Description Closes: #9891 I also think it's good to keep command name consistency. And moving `date format` to deprecated. # User-Facing Changes Running `date format` will lead to deprecate message: ```nushell ❯ "2021-10-22 20:00:12 +01:00" | date format Error: nu:🐚:deprecated_command × Deprecated command date format ╭─[entry #28:1:1] 1 │ "2021-10-22 20:00:12 +01:00" | date format · ─────┬───── · ╰── 'date format' is deprecated. Please use 'format date' instead. ╰──── ```
