Support husky v9

[timdp]

husky v9 changes the package.json format from:

"bin": "foo.js"

to:

"bin": {
  "husky": "foo.js"
}

Our current implementation only considers a single JSON string.

This PR takes the package.json contents and then uses sed to parse the CLI path from both kinds of expressions.

Tested using echo '{ package.json contents here }' | sed -e regexp. 🤞🏻
