feat(helm-chart): make charts Openshift compliant

[smuda]

Description

Allow removal of runAsUser and runAsGroup when running on openshift.

Fixes #3414

How to test

I've added a test under .github/scripts/.helm-tests and I hope that will run automatically together with the other tests, even though the github actions didn't run in my fork.

At least make helm-test works nicely :-).

Very nice start! Thanks for doing this. Just a few little comments on the documentation portions. The only big issue is that I think this belongs on its own page in the "Configuration" section.

To create a new page, move the contents to the contributing sub-section and follow the instructions in https://keptn.sh/stable/docs/contribute/docs/source-file-structure/#specifying-the-doc-structure to add this file to the mkdocs.yml file.

Hi @smuda thank you for your contribution! Do you please have the capacity to make the required changes in the following days? We are planning to do a release in the next days and we would like to have this fix merged until then. If you do not have the capacity, we will take over the PR.

Thank you in advance!

@StackScribe Thank you for the docs changes!

[smuda]

I rebased on top of main and handled most of your suggestions/comments. Could you please allow the rest of the tests to run?

[smuda]

Not many OSS have great documentation and you have even documented how to document. Impressive and awesome!

[odubajDT]

Awesome work! Some minor comments for the documentation :)
