Use husky.hooks to prevent warning on commit

[richdouglasevans]

Fixes an issue that caused the following warning to appear every time I committed in this repository.

Warning: Setting pre-commit script in package.json > scripts will be deprecated in v1.0
Please move it to husky.hooks in package.json, a .huskyrc file, or a husky.config.js file
Or run ./node_modules/.bin/husky-upgrade for automatic update

The issue was this pre-commit script: I've just done what the docs said to do and now there's no warning and the pre-commit hook is still run.

~/cypress/docs >> fix/husky >> git commit -am wip
husky > pre-commit (node v10.7.0)

> cypress-documentation@0.0.0 lint /Users/evansr1/cypress/docs
> echo 'Linting scripts...' && eslint --fix *.js cy_scripts/*.js scripts/*.js && echo 'Lint successful'

Linting scripts...
Lint successful

Used an explicit husky section in the existing package.json 'cos of the precedent established by the explicit section for jest.
