d3 should be injected into timeline.js and lint fixup

I am splitting off a side issue from

#2768925: Improve WebProfiler Library Dependency Discovery

I noticed that d3 is not injected into timelinejs as it should be.

Currently, the libraries injected ( see bottom of the file ) are

        }
    }

})(jQuery, Drupal, drupalSettings);

This is something that shows up in a javascript lint error check.

As I fixed it up I ran eslint just to check my change.

Unfortunately my changes were buried in a mountain of other lint errors.

Mostly 4 space indentation not 2 -- after I fix that the file was 22% smaller ( down from 8.6 Kbytes )
