[Self-hosted] can base for the self-hosted image upgraded?

[kwonoj]

What product do you want to improve? (e.g., Uploader, Web application, CLI, browser extension, Slack App, etc) Self-hosted public image

Is your feature request related to a problem? Please describe. We have warnings for some of the self-hosted images are based on EOL dist, for example self-hosted frontend https://github.com/codecov/gazebo/blob/c56690cd3ddf35e7ec49fcbb1534e3a81d9dcd28/docker/Dockerfile#L2 relies on alpine 3.17.

Per releases table (https://alpinelinux.org/releases/) it is no longer mainline supported version indeed. Curious if this is something considerable to upgrade to the supported version?

Describe the solution you'd like Set the base version to use latest stable (3.20 or 3.21) for the frontend, as well as other images if it uses similar version

Describe alternatives you've considered Preferrably we would like to stay with the published image, haven't thought of alternatives.
