Problem with tag generation with update_service command

[alexgorb2016]

Orb version:

v4.0.0

What happened:

with this code orb generates full sha1 tag for docker image, but we want to see it in a shorter way.
- aws-ecs/update_service:
cluster: << parameters.environment >>
family: "test-<<parameters.environment>>"
container_image_name_updates: "container=test-<<parameters.environment>>,tag=${CIRCLE_SHA1:0:9}"

Expected behavior:

image url should looks like 123456789 but not full sha1

Additional Information:

It works as expected with previous version of this orb.

This is a problem with the circleci cli, which is used to manage the environment variables in the configurations, for now, you can use the workaround provided on CircleCI-Public/aws-ecr-orb#329 until the fix is finished.
