[ENHANCEMENT] Extend the CI pipeline to upgrade generically from any version to any other version

[jessesimpson36]

Describe the use case:

Currently in our helm chart, we upgrade from the most recent released version for any minor release to the commit pointed to by the branch. However, the QA team brought up to me that they want to perform an upgrade that just changes the configuration. And their usecase specifically was about changing the configuration to include RBA.

My thinking is that there can be GHA inputs for 2 different chart versions. a from_chart and a to_chart and maybe another option for to_chart_extra_values so that you can have extra values.yaml options in the upgraded helm chart that are not present in the first-deployed chart.

Describe the enhancement/feature:
