documentation has errors

[stefanlack]

Current Behavior

The https://github.com/eclipse-tractusx/charts/blob/main/README.md file
distinguishes between stable and dev, but only the dev repository exists

From the README.md::

Dev Repository

helm repo add tractusx https://eclipse-tractusx.github.io/charts/dev

Stable Repository

helm repo add tractusx-dev https://eclipse-tractusx.github.io/charts/dev

On https://eclipse-tractusx.github.io/charts/stable/, a stable repository is documented, but it does not exists

Expected Behavior

Documentation should be valid.

Steps To Reproduce

> helm repo add tractusx https://eclipse-tractusx.github.io/charts/stable
Error: looks like "https://eclipse-tractusx.github.io/charts/stable" is not a valid chart repository or cannot be reached: failed to fetch https://eclipse-tractusx.github.io/charts/stable/index.yaml : 404 Not Found
