About modal version string is undefined when Grafana is not configured

[andrewazores]

Report generation and the minimal build setup is working well for me. Did you intend to leave the version string on the About page blank?

Looks like that's actually a bug on the frontend:

cryostat-web/src/app/Shared/Services/Api.service.tsx

Line 112 in 16410a7

return throwError(() => new Error(message));

Since there is no Grafana configuration, the Api.service fails the request, causing the "Grafana configuration not found" error popup. But this also prevents the version string from being correctly populated.
