[prometheus-kafka-exporter] Ability up update multiple charts in one PR

[rashmichandrashekar]

Is your feature request related to a problem ?

Is there a way to create a single PR to update multiple exporter charts for a common change? Ex - https://github.com/prometheus-community/helm-charts/pull/4389/files In this PR I have update the api version to be customizable, I want to make this change in all exporters. But I see the PR requires a single exporter to be mentioned in the title. Does this mean I have to open around 30 different PR in order to make this change for all the exporters?

Describe the solution you'd like.

Can make a single PR for the common change

Describe alternatives you've considered.
