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 appears that the only change made is to update the docker image tag being used in the deployment.yaml file for the tibuild application. The new image tag being used is v20240228-72-gd319bf4.

There don't seem to be any potential problems with this pull request as it is a straightforward update of a docker image tag. However, some suggestions that can be made are:

1. It's always a good practice to test the changes locally before creating a pull request to ensure that there are no unexpected issues.
2. Ensure that the new docker image tag being used is compatible with the current application code.

Other than that, the change seems simple and straightforward. Therefore, I suggest approving this pull request.
