Improve breadcrumb links for specific runner

Summary

On the admin page, there are two links within breadcrumb which target different pages, but are named same:

Steps to reproduce

1. Go to settings page Runners
2. Edit a runner

What is the current bug behavior?

When you edit a runner the breadcrumb has two links of Runners:

1. First Runners targets https://mygitlab.xyz/admin/runners
2. Second Runners targets e.g https://mygitlab.xyz/admin/runners/23

What is the expected correct behavior?

There are different labels for both links:

1. Runners to target https://mygitlab.xyz/admin/runners
2. uyiryV7x to target https://mygitlab.xyz/admin/runners/23 (the label should be the token of the runner)
