**Is your feature request related to a problem? Please describe.**

On EcrPushImage if you put more than one tag in pushTag the error for \n character compare.

**Describe the solution you'd like**

need implement a solution to manage more tha one tag like

**Describe alternatives you've considered**

Alternative is replicate more task of task: ECRPushImage@1 and chage the tag for each task

Start at the ECRPushImage@1 task and inspect how its pushTag input handles more than one tag, especially the newline comparison mentioned in the report. Done means the task accepts and processes multiple tags without the reported error, rather than requiring repeated ECRPushImage@1 tasks.
