ci: use Test Helm Chart github action

[neilime]

There is an existing action for testing helm chart: https://github.com/hoverkraft-tech/ci-github-container/tree/main/actions/helm/test-chart

I guess you can use it instead of "reinventing the wheel" here:

helm-chart-postal/.github/workflows/__shared-ci.yml

Line 16 in a9d5f7f

@fredleger I've setted the "golden path" CI.

The helm tests are failing because of mariadb. In my opinion the version of the dependency is quite old, it should be updated.

@fredleger when you will have time to check this, it will be the last thing to finsh CI on this project.

Thanks
