Unable to remove new line character in pipeline?

Team,

I have created this task 

- task: AzureCLI@1
displayName: 'Tag Prod Containers'
inputs:
azureSubscription: Production
scriptLocation: inlineScript
inlineScript: |
readarray -t images <<< $(grep -E 'repository|tag' $(Pipeline.Workspace)/values/higher-values.yaml|awk '{print $2}')
registry=$(awk -F. '{print $1}' <<< ${images[0]}|tr -d '\n')
kongingress=$(awk -F/ '{print $2}' <<< ${images[0]}|tr -d '\n')
kong=$(awk -F/ '{print $2}' <<< ${images[2]}|tr -d '\n')
echo "------------------"
sed -z 's/\n/ /g' <<< $(tr -d '\n' <<< ${images[2]})@${{ parameters.Digest_Id }}

sed -z 's/\\n/ /g' <<< $(tr -d '\n' <<< ${images[2]})@${{ parameters.Digest_Id }}
echo "------------------"

But output is always coming like this. A new line after kong word.
