Documentation needs updating

I'm currently creating an index template per dataset, which includes both component templates.
For example, index template `logs-endpoint.alerts-.` includes both component templates `logs-endpoint.alerts@package` and `logs-endpoint.alerts@custom`.

I've had some errors while adding and I've been going through the [integration documentation](https://docs.elastic.co/en/integrations/endpoint) for Endpoint and there's something I believe is incomplete.

For the data type `logs`, according to the documentation, we have the following datasets:
`alerts`
`file`
`network`
...

What I see in my Elastic cluster though, is that the index templates and their index patterns are not exactly like this. They're more like:
`alerts` -> `alerts`
`file` -> `events.file`
`library` -> `events.library`
`network` -> `events.network`
...

It also seems `events.api` is missing here as well.

I think an update of the documentation is needed here to show the real datasets used here.
