Fix version number of helm chart (#9576)

**What this PR does / why we need it**:

There were 2 commits for the helm chart with the same version number. In
this case the build scripts only releases 1 new helm chart, containing
the first commit. This PR adds a new version so a helm chart will be
created that contains the later PR.
