Golden files need to be updated as version is updated in the
`Chart.yaml` file. This commit adds the step to update the golden
files in the release pipeline.
To make that possible, The following additional changes are also
required:
- `Go.Work`: This adds support multi-module projects as we will
have the tests along with the operator in sub-folders. This
is required to run go cmds from the root directory. (like
running tests in this case).
- `.helmignore`: This updates the Helm chart to ignore the `/ci`
folder during helm packaging as those are not required for
users of the chart.
