Missing Upgrade Package gitlab-ce 13.8.8 for sles15

Hello everyone,

i have started the upgrade path from an older gitlab-ce to newest,
but now i am missing the intermediate version gitlab-ce-13.8.8-ce.0.sles15.x86_64.rpm and had to stop for now.

For the Upgrade Path Version 13.8.8 is mandatory,
but not to be found under RPM Packages

As far as i know all other Version for SUSE x86_64 before and after 13.8.8 exists.
Only gitlab-ce-13.8.8-ce.0.sles15.x86_64.rpm is missing.

Some Ideas why this Version is missing and where to get them?
