Set chart version to be the same as app version
We kept these versions independent in the beginning, I believe largely because we didn't want to have to ship a GitLab patch if we needed to fix something in the charts.
We should evaluate if the charts are mature enough now, that the risk and frequency is acceptable (low).
A couple questions to evaluate:
- When was the last time we shipped an out of band chart release due to a major bug?
- Are there other reasons to ship out of band releases of the chart?
