Error in API docs?

**Describe the bug**
The REST API docs for the [List of process definitions API](https://www.flowable.com/open-source/docs/bpmn/ch14-REST/#list-of-process-definitions) state the following for the "latest" parameter:

> Only return the latest process definition versions. Can only be used together with 'key', 'keyLike', 'resourceName' and 'resourceNameLike' parameters, using any other parameter will result in a 400-response.

This does not seem to be true in practice. If you omit those parameters but still use "latest=true" you do get the latest version of each process definition with an HTTP error 200 status code.

I assume the "Latest version" filter in Flowable UI > Admin > Process Engine > Definitions uses the same API and there it also works.

**Expected behavior**
I guess if this is known to consistently work, the docs should be adapted. If not, I guess responding with an actual HTTP 4** error response would be better.

**Additional context**
Tested against Flowable 6.7.2 and 6.8.0.

Start by reproducing the List of process definitions API request with latest=true and without the documented filter parameters, using the behavior described for Flowable 6.7.2 and 6.8.0. Compare the result with the API documentation linked in the issue; done means the implementation and documentation agree about whether the request is valid and what response it should produce.
