feat(reports): support github code scanning output format

[apr-1985]

Is your feature request related to a problem? Please describe.
Currently the Kics Sarif output format uses the Error, Warning etc format for output in sarif.
This does not play 100% nicely with GitHub which works best with a Critical, High etc format.

It means that Kics results are not seen at the same level as my other app sec tooling and I do not see them in security dashboard overview charts etc.

I can see in the sarif code that you convert from Critical to Error etc https://github.com/Checkmarx/kics/blob/master/pkg/report/model/sarif.go#L17-L23

Describe the solution you'd like
I would like there to be an output format for GitHub that gives the results in a format that plays best with Advanced Security.

Someone from GitHub has given a solution on the Kics Action repo here Checkmarx/kics-github-action#99

Describe alternatives you've considered
In all honesty not using Kics and using another tool that integrates better.

Additional context

Kics results have their own ratings separate to the main GitHub supported ones

Means that Kics doesn't feature in any reports or trend analysis etc where as other 3rd party tools do
