docs: Fix lint-staged link (#237)

The link to the lint-staged docs is broken, on the website page (https://mrm.js.org/docs/mrm-task-lint-staged).

It redirects to: https://github.com/okonet/lint-staged/blob/master/readme

So fix it up with: https://github.com/okonet/lint-staged/blob/master/README.md#-lint-staged---

packages/mrm-task-lint-staged/Readme.md
