[frontend] Image reference specifying tag with digest should work

Environment

• How did you deploy Kubeflow Pipelines (KFP)? Google Vertex AI
• KFP version: 1.8.6 (Python 3.10.6)

Steps to reproduce

Use image reference containing both tag and digest, e.g., gcr.io/some-project-id/some-product:0.0.1@sha256:0123456789abcedf0123456789abcedf0123456789abcedf0123456789abcedf

Expected result

Pipeline should run but receiving google.api_core.exceptions.InvalidArgument: 400 Invalid image URI gcr.io/some-project-id/some-product@sha256:0123456789abcedf0123456789abcedf0123456789abcedf0123456789abcedf instead.

Materials and Reference

Using either tag (e.g., gcr.io/some-project-id/some-product:0.0.1) or digest (e.g., gcr.io/some-project-id/some-product@sha256:0123456789abcedf0123456789abcedf0123456789abcedf0123456789abcedf) works.

Expected image reference including both tag and digest is very useful for identifying correct images which is complex with just using digest.

Example stack trace:

The above exception was the direct cause of the following exception:
