husky -> simple-git-hooks (#10601)
`Lint staged` along with `mrm` recently migrated from `husky` to `simple-git-hooks`.
It is reflected in their [docs](https://github.com/okonet/lint-staged):
> It will install and configure simple-git-hooks and lint-staged depending on code quality tools from package.json dependencies so please make sure you install (npm install --save-dev) and configure all code quality tools like Prettier, ESlint prior that.
Migration brought these benefits for users:
* lighter `node_modules`
`simple-git-hooks` (10 kb) is lighter then husky4 (1mb) and husky5 (25kb)
* Out of the box `Yarn 2` support
* No worry for licensing.
Simple git hooks has MIT license, like husky 4
