Include Servicemontiors and Podlogs CRDs in grafana-agent helm chart

[balazs92117]

PR Description

The new grafana-agent flow helm chart can automatically install CRDs. But it includes only Podlogs. With this PR it will include Servicemonitors and Podmonitors CRDs too. Servicemonitors are widely used by a lot of helm charts, and the "flow version" of grafana-agent also supports it via prometheus.operator.servicemonitors

Which issue(s) this PR fixes

To use Servicemonitors in other helm charts, first I have to install that CRD. The grafana-agent helm chart already maintain a CRD, so it would be easier to include Servicemonitors CRD in it, so we don't have to install that CRD separately.

I encountered the same issue here, I'm migrating from Grafana Operator to Flow and when I tried to deploy for example kube-state-metrics and create the serviceMonitors related to them, I needed to install manually the CRDs from prometheus-operator to be able to scrape my personal serviceMonitor configuration.
