[JENKINS-73065] Improve documentation for Remote API access

When trying to access the coverage results of a build through the api as described in the documentation we are getting a 404.

For a build under https://some.jekins.server.com/job/SomeFolder/job/Project/job/Repository/job/Branch/95/

we would try to get the coverage results through https://some.jekins.server.com/job/SomeFolder/job/Project/job/Repository/job/Branch/95/coverage/api/json?pretty=true

but this results in a 404

Seems like this is supposed to work (bug maybe not for multi-branch pipelines?) or if we are doing something wrong to make this work.
