Make Cosmovisor Directory and Copy Binary

Since the folder name v8-Rho contains capitalized letters, please check your cosmovisor version to ensure that it complies with the version stardard.

mkdir -p $HOME/.gaia/cosmovisor/upgrades/v8-Rho/bin
cp $HOME/go/bin/gaiad $HOME/.gaia/cosmovisor/upgrades/v8-Rho/bin
