Description
Expected Behavior
I would expect a valid image digest (like docker.io/foo/bar@sha256:abc123) to be accepted by tilt when using the outputs_image_ref_to field of custom_build.
Current Behavior
Error: Output image ref in file /foo/bar/ref.txt was invalid: Expected reference "docker.io/foo/bar@sha256:afb1ca867b4b0cdf1e948278e874429301daea856f4bf2c698c5cb51d4c336c6" to contain a tag
Image digests are truly immutable and it is surprising behavior that they wouldn't be supported based on https://docs.tilt.dev/custom_build.html#why-tilt-uses-immutable-tags

Research direction
Start at custom_build's outputs_image_ref_to handling and the image-reference validation that currently requires a tag. Compare the documented immutable-tag behavior with digest references such as docker.io/foo/bar@sha256:abc123; done means valid digests are accepted without regressing tagged image references.
