[Cloud Security] Set DataTable row density to expanded (#191138)

## Summary

Due to a [recent change](https://github.com/elastic/kibana/pull/188495)
on the UnifiedDataTable component, the density was set to default to
`compact`. This PR overrides this property to `expanded` in order to
keep consistency with the Design specs.
