deployment/alerts: add missing description for VMagent alerts ()
The 3 alerts for VMagent:
- `RejectedRemoteWriteDataBlocksAreDropped`
- `TooManyScrapeErrors`
- `TooManyWriteErrors`

missed the description annotation.
I moved the summary to description and added a generic summary to these
alerts.

### Checklist

The following checks are **mandatory**:

- [x] My change adheres [VictoriaMetrics contributing
guidelines](https://docs.victoriametrics.com/contributing/).
