upgrade production logging cluster to 7.8
refs: https://gitlab.com/gitlab-com/gl-infra/infrastructure/-/issues/10094
nonprod should be upgraded first
We can do it ourselves or ask support to do it for us.
Let's wait a couple of weeks for the 7.7 release to stabilize and for the cluster to operate without any issues
7.7 was specifically called out by support as having multiple memory utilization improvements (which is something we struggled with in the last few weeks)
