Build: run plugin examples tests every hour

[mckn]

To catch issues introduced in Grafana that might affect plugins we should run the plugin examples tests every hour.

or maybe even better. Run it based on a push to master event in grafana/grafana

I think the second option of a push to master of grafana/grafana whenever files change in packages/**/ would be more advantageous and is relatively easy to do in drone. 👍

@jackw how often do we run currently? I imagine we want to discuss this in relation to the new e2e tests running in grafana and as part of the broader topic on the purpose of these examples

They run ones every 24h and when someone push something new to main.
