Show project number, average test coverage and job number on graph tooltip

Release notes

Problem to solve

As an application dev director/manager, i want to see why there's a big change in the Group Code Coverage graph, so I can ease fears of the graph changing a lot day to day.

Intended users

• Sasha (Software Developer) - who has to answer why the graph dropped off one day.

User experience goal

The user should be able to see a tooltip when hovering on graph points on repository analytics to see what the average, number of projects and number of jobs that made up that number was each day.

This helps explain to the user why there was maybe a sudden drop (a bunch of new projects added coverage calculation and have poor coverage)

Proposal

We should be able to add the extra data to the existing tooltip. @shampton to confirm

Availability & Testing

What does success look like, and how can we measure that?

Acceptance criteria

• The tooltip data is accurate / matches the table for the selected day(s)

What is the type of buyer?

Is this a cross-stage feature?
