cent OS image fails to build

[haiqi96]

Bug

In current workflow, the centos image build fails on an error
curl#6 - "Could not resolve host: mirrorlist.centos.org; Name or service not known"

This seems to be due to cent OS EOL in 2024 June, which caused the mirrorlist.centos.org to be removed.

A possible solution is to update all .repo files, which will result in a quite messy DockerFile.

Based an offline conversation with Kirk, cent OS is used by a very specific group of users. Perhaps we should first understand why they rely on cent OS 7 and decide whether to fix this bug or deprecate cent OS 7.4

Environment

the local env doesn't matter

Reproduction steps

commit any change that would trigger workflow rerun and push it to your own repo.

For example, a simple change would be adding/deleting a comment in the cent OS's dockerfile.
