Preserve backticks in Helm ref docs

The Cloudflare builds were failing, and I noticed this error in them:
```

```

the update-ref-docs was removing backticks from the Helm ref docs, I'm not sure why. But I think adding it will prevent the build from thinking this `${KMCP_VERSION}` variable is jsx that it needs to interpret.
