[Dashboard] fix Export CSV doesnt work (#198547)

Closes #198517

#193644 refactored Dashboard
services. Part of this refactor moved `fieldFormats` from
`data.fieldFormats` to getting `fieldFormats` directly from the
fieldFormats plugin. That is because `data.fieldFormats` is marked as
deprecated. The problem is that the fieldFormats plugin was not defined
under `requiredPlugins` and thus was undefined at runtime.

### Test instructions
1) install web logs sample data
2) open web logs sample data dashboard
3) hover over "[Logs] Response Codes Over Time + Annotations" panel and
select "three dots" icon. Then select "Download CSV". Verify there are
no errors in web browser console and CSV is downloaded.
