add Helm chart (#2)

**Testing steps**
- Download the `kmcp` cli to easily spin up a new mcp server.
- Add kmcp binary location to your path `export
PATH="<path_to_kmcp_bin>:$PATH"`
- Run the following script in the root directory of the repository to
test out the published helm chart and controller image alongside an mcp
server with the echo tool. Assumes you have npx installed and your
docker config is located at `~/.docker/config.json`.

(demo script still wip)
