Add Husky pre-commit configuration, #318.

[tormi]

How to test:

1. Get this branch
   git clone git@github.com:wunderio/drupal-project.git
cd drupal-project
git checkout feature/husky
2. Start Lando
   lando start (or lando rebuild if you've working on existing Lando project)
3. Create example js file
   echo 'var foo="bar"' > web/modules/custom/phpunit_example/example.js
4. Add the file to GIT
   git add web/modules/custom/phpunit_example/example.js
5. Try to commit
   git commit

It seems this overwrites Code Quality hooks so rest of the scanners don't execute anymore (phpcs, psalm etc).

Also this scans all the files, Code Quality scans only the committed files.

Also this scans all the files, Code Quality scans only the committed files.

Added lint-staged setup to overcome this. However, since we're using lando npm run pre-commit within Husky, it also requires git config --global user.email "you@example.com" & git config --global user.name "Your Name" inside the node container ;)

Test was running successfully only on staged file after I've defined git config flags noted above:
