Update GH Action Super-Linter and README (#7951)

Updates the GH Action and makes a small update to the README to test
changes.

A missing install step for Windows Terminal using Scoop has been added.
The versioning of Super-Linter was also switched to v3 to allow
auto-updates within the v3 series. This can be version-pinned again if a
breaking change comes later. The current updates fix some bugs and bump
the linters utilized. 

## Validation Steps Performed
Validation will be shown in the build steps.

Closes #7934
