Broken link on the documentation page

[rbroen]

Bug Report

The documentation page for this module could do with some tlc. Unfortunatly, the link at the bottom states "Found a mistake or want to contribute to the documentation? Edit this page on GitHub! ", but the link leads nowhere: https://github.com/mezzio/mezzio/edit/master/docs/book/v3/features/router/fast-route.md

Expected behavior

The link at the bottom of the documentation page should link to the documentation page in a github repository.
