Outdated nginx version used by chart

[MichaelEischer]

According to https://hub.docker.com/_/nginx only nginx 1.26 and 1.27 are still supported. However, the helm chart currently pulls in nginx 1.23:

cortex-helm-chart/values.yaml

Line 1248 in e9f1005

tag: 1.23

What do you think about switching to the alpine version of the docker image?

yeah... renovate seems to be disabled 🙈
