Missing digest, revision and short revision in tags

It seems that in some cases the Digest, revision and short revision is missing for some tags, now that the UI prominently shows them this bug is quite visible:

We should discuss the best way to address this, probably an MVC step would be to add proper copy when something is missing.

Proposal

Implement a warning flag w/ tooltip to indicate to users that something is wrong with tag. Remove the expandable detail UI entirely.

First iteration

Further information

The tag missing a manifest could also create an error when a user attempts to delete the tag.

• It will certainly fail if the tag in question is in a 3rd party registry
• It may or may not fail if it is in the GitLab Container Registry.

Because of this, we should disable the checkbox and delete buttons for the tag in question.

⚠ Note, the disabled buttons are not included in the design comp above.
