Adjust 'Release Guidelines Checks' dashboard for TRG 4.02

[evegufy]

Is your support request related to a problem? Please describe.

on the 'Release Guidelines Checks' dashboard, portal(backend) is shown as apparently not compliant with TRG 4.02 but portal-backend is actually compliant with that TRG, see:
https://github.com/eclipse-tractusx/portal-backend/tree/main/docker
https://eclipse-tractusx.github.io/docs/release/trg-4/trg-4-02#description

also for cx-iam the dashboard shows non compliance with TRG 4.02.: I opened eclipse-tractusx/eclipse-tractusx.github.io#383 for that

Describe the solution you'd like
Adjust dashboard to show portal and cx-iam compliant with TRG 4.02.

Hi @evegufy, your PR was approved by @SebastianBezold, think your waiting for feedback from @AngelikaWittek .

For the Release Guidelines Checks we have to check if the result for desired systems.

@carslen I'm reopening the issue because the portal(backend) and cx iam shown are still shown as not compliant with TRG 4.02 on the 'Release Guidelines Checks' dashboard,

little update for cx-iam

but portal-backend seems working differently

@FaGru3n, @evegufy yes, that's known issue at the moment we don't support image aliases in Dockerfiles at our check. I've just created an issue to fix that in nearest future - eclipse-tractusx/sig-release#546
