client: fix Consul version finterprint (#17349)

Consul v1.13.8 was released with a breaking change in the /v1/agent/self
endpoint version where a line break was being returned.

This caused the Nomad finterprint to fail because `NewVersion` errors on
parse.

This commit removes any extra space from the Consul version returned by
the API.
