Update extlinks strings to use a format string (pypa#555)

mayeut · hrnciar · commit 3bbaa9df6c39 · 2022-06-24T14:11:23.000+02:00
This addresses a warning in Sphinx 5, regarding the missing` %s` in
these strings.

```
extlinks: Sphinx-6.0 will require a caption string to contain exactly one '%s' and all other '%' need to be escaped as '%%'.
