If remote_host has a newline, deployment fails with ssh: Could not resolve hostname

[Fred van Dijk]

This is an easy error to make and hard to catch. Only if you enable debug on the run, you see that the remote_host variable only has a starting ' quote, but not an ending quote like the other variables.

In the github environment UI it is very easy and invisible if the variable has a newline. Can we add somethiing like:

when the remote_host variable is used?

Alternatively we could also catch it in the GHA workflow file when the remote_host variable is assigned in the with: arguments, but that's repetitive boiler plate every time you use the action.
