chore: use grafana/kindsys and update schemas

[Duologic]

Regenerate all 'merged' schemas.

Like previous update, this includes some skipPlugins, mainly because we want timeseries:

grafana/grafana ➜ git diff public/app/plugins/gen.go

 var skipPlugins = map[string]bool{
-       "canvas":      true,
-       "candlestick": true,
-       "timeseries":  true,
+       //"canvas":      true,

+       //"timeseries":  true,

Most notably, this now includes the Prometheus query schema.

First commit is a change, second is only generated content.
