Update centpkg-minimal to 2.1.0-5 from EPEL 10 in testing-farm-tag-repository

I want to use centpkg-minimal from EPEL 10 in a CentOS Stream distgit repository test suite. It has been recently added to EPEL 10 - https://src.fedoraproject.org/rpms/centpkg-minimal, https://koji.fedoraproject.org/koji/buildinfo?buildID=2581629 Unfortunately, testing farm repository contains the older 2.1.0-4 version which, among others, points to sources.stream.rdu2.redhat.com rather than the public https://sources.stream.centos.org/sources.
