[release-v2.3] Set GRAFANA_VERSION used throughout shared lookups (#3101

)

* Set GRAFANA_VERSION used throughout shared lookups (#3091)

It was working in "next" because the fallback behavior is to use the page's version for any "SOMETHING_VERSION" lookup.
Therefore, the `docs/shared` lookup coincidentally targeted "next" which exists in the Grafana documentation.

Now that we have cut a new release with these docs, the released version is being used which is causing errors because `v2.3.x` is not a valid Grafana version.
