Document Kubernetes installation with the HelmForge Helm chart

Hi maintainers,

I was looking through the project documentation and did not find a Kubernetes installation section using Helm. If I missed an existing official page, please point me to it and feel free to close this.

HelmForge now publishes a production-oriented Helm chart for GitHub MCP Server:

- Documentation: https://helmforge.dev/docs/charts/github-mcp-server
- Chart source: https://github.com/helmforgedev/charts/tree/main/charts/github-mcp-server

The basic installation flow is intentionally simple:

~~~bash
helm repo add helmforge https://repo.helmforge.dev
helm repo update
helm install github-mcp-server helmforge/github-mcp-server --namespace github-mcp-server --create-namespace
~~~

The chart is meant to provide a Kubernetes-native path for users who want to run GitHub MCP Server on their own clusters, with explicit values, pinned upstream images, and common production surfaces such as persistence, service exposure, probes, security contexts, and optional integrations where applicable.

Would you be open to adding a short Kubernetes / Helm installation section to the documentation that references this chart as a community-maintained deployment option?

If that direction makes sense, I would be happy to prepare a documentation PR with a concise install section, links to the HelmForge chart documentation, and any wording you prefer around support boundaries.

Locate and read the existing installation documentation, then review the linked HelmForge chart documentation and its basic Helm commands. Done means adding a concise Kubernetes/Helm installation section that links to the community-maintained chart and clearly states the support boundary.
