[FEATURE]: Automatic update of helm charts with latest image version

[donatwork]

Describe the solution you'd like As developers and maintainers We would like to use dependabot to automatically update our Helm charts with the latest image versions So that we can save developer time and reduce errors in our release processes.

Describe alternatives you've considered We have tried a number of pipeline items but this one seems to work OK.

Additional context Result of investigative work done by @eric-young.
