lando pull should pass in flags to acli, at the least the --on-demand flag

[nalipaz]

The lando pull command works great but it seems that it doesn't pass in flags that are available. Due to the output provided by acli it is seemingly confusing why the flags passed in won't work as well.

% lando pull

 [INFO] Using a database backup that is 21 hours old. Backup #269581476 was created at Fri Dec 21 3:47:05 UTC 2023.

        To generate a new backup, re-run this command with the --on-demand option.

As seen here the acli command outputs the detail about the --on-demand flag. That said, it was a bit confusing at first when that flag had no affect on the command. I realized however and would like to request that we be able to pass in that flag to lando pull and it will subsequently pass it into acli.
