Install gzip into gitlab-rails containers
What does this MR do?
In gitlab-org/gitlab!105115 (merged) we are adding a compression step via gzip
to write smaller diagnostic report files to disk. The Rails image already had gzip
installed (probably available by default?) but I think it would be good practice to make sure this remains installed should we decide to shrink the base image elsewhere.
It will also provide a reference point in case we want to swap out gzip
for something more powerful such as zstd
.
NOTE: Diagnostic reports are currently a SaaS-only feature. It is not part of Omnibus. There are no plans currently to make it more widely available either.

The impact any change in container size has should be evaluated. gzip is already installed: docker run --rm -t registry.gitlab.com/gitlab-org/build/cng/gitlab-rails which gzip
