Reverts #219

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 looks like the changes aim to revert a previously added feature of adding a tiflow-engine docker image. The diff shows that the tiflow-engine container image has been removed from the packages.yaml.tmpl file.

However, without more context about why this feature was added and why it's being removed, it's difficult to determine whether this is the right decision. Therefore, it would be helpful to have more information about the reason for the revert.

Assuming that the revert is necessary, the changes look straightforward and do not introduce any new code. Therefore, the risk of new bugs is minimal.

As for suggestions, it would be helpful to provide more information about why this feature was added and then reverted. If there was a specific issue or problem with the tiflow-engine image, it would be useful to know what that was. Additionally, it's always a good idea to test and verify that the changes made don't have any unexpected consequences.
