feat: disable auto refresh cache image for master&8.4

[purelind]

Since 8.4, the base image has been switched from centos7 to rocky8, so we no longer use this task for cache image updates on branch master and 8.4.

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 related to disabling the auto-refresh cache image for the master and 8.4 branches. The diff shows that the changes involve removing the build_branch() calls for the master and release-8.4 branches.

There are no immediate potential problems that I can see with this PR. However, it's important to ensure that the cache image is being updated properly for other branches.

As for fixing suggestions, it would be helpful to add a comment explaining the reason for disabling the auto-refresh cache image for the master and 8.4 branches. Additionally, it may be a good idea to make sure that there are no other branches that also need to have auto-refresh disabled.

Overall, this seems like a reasonable change that should not cause any issues for the pipeline.
