[infra][puppet] Old mirror contents in apt-puppetlabs

Hello Infra team, I noticed the contents in the apt-puppetlabs directory in our CI mirror are old. The mirror repository provides puppet 6.23 while the upstream repository provides newer versions such as 6.28. Recently we bumped puppetlabs-mysql in our CI to 13.0.0 which requires puppet >= 6.24.0 and our Ubuntu jobs are failing now at a quite early stage because of the old puppet package. May someone please look into this ? I've checked mirror.iad3.inmotion.opendev.org and mirror.bhs1.ovh.opendev.org but it seems the contents in the directory have not been synced since July, 2021. Thank you, Takashi
