[docs] workflow to handle KMCP_VERSION

doc builds are breaking with errors like:

```
09:43:27.077	Error occurred prerendering page "/docs/kagent/resources/helm". Read more: https://nextjs.org/docs/messages/prerender-error
09:43:27.077	ReferenceError: KMCP_VERSION is not defined
```

it looks like the ${KMCP_VERSION} does not have codeticks so it breaks the build

follow up to #280
