Add Statistics category to the contextual navigation at a project level
At a project level:
- Add new Statistics category to the contextual navigation (sidebar).
- Move Charts (currently within Repository) to the new Statistics category.
- Move Cycle Analytics to the new Statistics category.
- Move Contributors to the new Statistics category.
- Move Members to the new Statistics category.
Research to support this decision: https://gitlab.com/gitlab-org/ux-research/issues/43
**Order of the new elements**
- The Statistics category will appear below CI/CD and above Wiki.
- The ordering within the statistics category is as follows: Cycle Analytics, Contributors, Members and Charts.
- Based on the points above, the new structure of the contextual sidebar at a project level will be as follows:
