I have already done a preliminary review for you, and I hope to help you do a better job.
Based on the provided information, the pull request seems to only add some comments to the Dockerfile and update the base image from pingcap/centos-stream:8 to PingCAP-QE/ci-dockerfile/blob/master/jenkins/amd64/alpine-3.14.6. No actual code changes are made.

However, there are some potential issues:

• The added comments do not provide much value and may clutter the codebase.
• The change of the base image may introduce compatibility issues or other unknown problems.

Suggestions:

• Remove the added comments as they do not add any value to the codebase.
• Before changing the base image, the contributor should provide a clear reason for doing so and verify that the new image does not introduce any compatibility issues or other problems.

Based on the title and the diff, it seems that the only change in this pull request is the addition of some comments to the Dockerfile and removing a trailing whitespace. Therefore, there are no potential problems that could be introduced by this change.

As for fixing suggestions, it would be good to make sure that the comments added are informative and useful to other developers who may be working on this codebase in the future. Additionally, if the author of this pull request plans to compose a multi-arch image, it would be helpful to provide more specific details on how this will be done and what the benefits of doing so are.
