Runner number does not link to runner admin page.
### Summary
As admin of the gitlab instance, runner number on a job used to link to the admin page `/admin/runners/{#}`
### Steps to reproduce
Go to any job and it won't work.
### Proposal
- `jobs/:id.json` will send a new property `path` under the `runner` property if the user has admin access.
- FE will show the link if `runner.path` is available
### Design
- Runner link in job detail page sidebar should link towards runner detail page if you are an instance administrator
