Suggested update to documentation/readme

[darcyparker]

Please consider strengthening the recommended prepare script in the docs.

Sometimes the suggested "prepare": "husky install" script fails because it assumes the $CWD is a git repo. There are edge cases where it is not... (some builds on docker don't clone the whole git repo). And another edge case is that husky is a devDependency and only the dependency packages are installed...

I like "prepare": "husky install || exit 0" @Titan196 mentioned in #1213 (comment)

Another possible solution: "prepare": "git rev-parse &>/dev/null && husky install || echo 'Not git repo skipping husky install'" which makes it clear we're testing for the $CWD being a git repo... But perhaps not as good a solution if the user installed as husky as devDependency and didn't install the dev dependencies.
