[francisfuzz]

This PR updates package.json to include husky as a devDependency, moving the precommit step from scripts to husky as suggested by their documentation.

@francisfuzz Can you remove the change to dist/index.js in this? Then should be good to go.

I'll do that, will follow up here when it's finished 👌

@jclem - While I'm totally up to make that change, I'm wondering why you don't want that newly updated dist/index.js file there? Is it because the changes in scope are only related to husky rather than source file itself?

As an aside -- I'd like to figure out what's happening on my local machine that's actually hardcoding values of my local copy into the dist/index.js upon compilation of the Typescript source file. Not sure what's happening there.

@francisfuzz I think it's something with your local setup—when I reproduce this PR on my own branch, dist/index.js isn't changed (which it shouldn't be, since husky wouldn't be required in the distribution build for this action).

Ugh, I tried fixing it but can't get rid of the newline.
