CKV_DOCKER_7 only reports on first occurence of issue

[Kemosabert]

Describe the issue
The rule CKV_DOCKER_7 only reports the first occurence of the rule in a file and does not flag on other stages also not pinning the image to a specific tag.

Examples

FROM test.dkr.ecr.eu-west-2.amazonaws.com/my-registry/baseimage as baseImage

# do bunch of things here

FROM test.dkr.ecr.eu-west-2.amazonaws.com/my-registry/migrations-runner:latest as setup
# do bunch of more things here

ENTRYPOINT ["/entrypoint.sh"]

I would expect it to flag both FROM statements as problematic, but it only flags the first one. Once that is fixed, the 2nd one will also be flagged.

Version (please complete the following information):

• Checkov Version [3.2.327]
