Chart v0.8.1 was not published

[aceat64]

The action failed trying to run ct lint as it didn't detect any changes to the chart:

https://github.com/zilliztech/milvus-operator/actions/runs/6180913848/job/16778106289

A simple workaround for this may be to run ct lint --all which bypasses the change detection. This should be fine since the workflow is only run on pushes for tags.

I manually release the chart in github pages, now it should be available. I'll check the action later
