Bump stable tag to 28.0.6 or even to 29.0.3

[Zottel92]

Hello,

since 25th Jun the rollout of Version 28.0.6 is the 100% rolled out version of V28 (with this commit: update-server-commit

But even earlier this commit update-server-commit from the 23th of may the rollout from 28 to 29 was set to 100%.

Would it make sense to bump the stable tag to 28.0.6 or even to the right now 100% rolled out version of 29.0.3? Or is there a bug blocking this?

Sorry that I always ask, but there seems to be no such overview available. Otherwise I could look into and of possible help to work on them. Or would it make sense to open Pull-Requests for bumping the stable version myself and then discuss possible blocking issues in the Pull-Request?

Thank you for the work on this container-image. Best regards
