Typo in documentation (`./bin/franka_interface configs/charmander.yaml`)

Hi,

`./bin/franka_interface configs/charmander.yaml` should be changed to `./bin/franka-interface config/charmander.yml` on this page: https://zhuyifengzju.github.io/deoxys_docs/html/tutorials/running_robots.html

That's all. Thanks for the great library!
