fix: adjust upgrade orchestrator scp quoting

[gartnera]

Description

current height is 222, waiting for 224
current height is 223, waiting for 224
current height is 224, waiting for 224
waiting 10 seconds for node to restart...
version did not change after upgrade height, maybe the upgrade did not run?

scp: ~/.zetacored/config ~/.zetacored/os_info ~/.zetacored/config ~/.zetacored/keyring-file ~/.zetacored/keyring-test: No such file or directory
sed: can't read /root/.zetacored/config/client.toml: No such file or directory

It looks like quoting rules changed with the debian/ubuntu version upgrade in #2285. Another reason for #2134.
