Add Helm chart for Excalidraw deployment

This commit introduces a complete Helm chart for deploying
Excalidraw, a virtual whiteboard for sketching diagrams, on
Kubernetes. The chart includes essential templates for
deployment, service, ingress, horizontal pod autoscaler,
and service account, along with a README and values
configuration. Key features include customizable image
repository, resource requests, autoscaling support, and
ingress configuration options.

These changes facilitate easier deployment and management
of Excalidraw in Kubernetes environments, providing
users with a structured approach to configure their
installations. No breaking changes are introduced.
