GH Action Push charts to 8gears.container-registry.com does not work

[Vad1mo]

the job did not push the chart to the reigstry.

https://github.com/8gears/n8n-helm-chart/actions/runs/9582143232/job/26420470725

1. I suspect there was no package build
2. the push did not pick up the package in the directory.

Here are some references how others are doing it.
