Feel free to support helm oci registry

[LinuxSuRen]

I made this in my own project. If you belive it's worth to do it, I'd like to help on it.

感谢，不过我这里可能有些非标准的操作，比如我需要在某一个具体的版本上持续更新helm chart，比如 v6.3.9这个helm chart version 需要持续修复一些bug，而保证版本号不变，我不知道这些是否可以在oci registry上完成，但目前我都是在自建的helm repo和github helm repo上直接覆盖的

It's totally ok for your use cases.
