I have already done a preliminary review for you, and I hope to help you do a better job.

Based on the pull request title and description, it seems that the changes are aimed at fixing a regular expression in the artifact_helper.go file. The regular expression is used to validate image source synchronization.

The diff shows that the change is a one-line modification of the regular expression used to validate source image synchronization. The original regular expression had a typo in the version part, where the dash symbol was followed by a digit instead of a plus sign.

There are no potential problems identified in this pull request. The change is simple and straightforward, and the fix seems to be appropriate.

However, one suggestion for improvement is to add a test case that checks for the validity of the regular expression. This would ensure that future changes to the codebase do not break the regular expression.

Additionally, it would be helpful to provide more context in the pull request description, such as why the original regular expression was incorrect and how this fix resolves the issue.
