[Documentation]: Helm repo specification

[clayrosenthal]

In your helm chart docs you don't specify how you configured the helm repo. I would like to see what repo you use, ie:

helm repo add helmchart <url>

Should it be https://charts.blue-atlas.de or some gh-pages url? Seems like the gh-pages branch is for the docs not hosting the helm chart. Perhaps there's some way for it to do both.

Or if there's some way to be installing via oci:// ie:

helm install librechat oci://ghcr.io/danny-avila/librechat-chart:latest

[clayrosenthal]

Looks like a big improvement was added to the helm charts (#3638), but it's still only available by pulling the repo. Could you please either weigh in on where that chart and the new librechat-rag-api are being published or take a look at my PR (#7256) to publish to ghcr.io?
