Update for PureScript 0.14

[thomashoneyman]

👋 Hi Gary!

This PR updates quickcheck-laws for compatibility with PureScript 0.14. I've opened this pull request instead of waiting for the official release because freeap depends on this library, and Halogen depends on that library, and I think users would really appreciate being able to use Halogen right off the bat when PureScript 0.14 is released.

Specifically, this PR:

• Updates tooling dependencies for compatibility with the new compiler (this is backwards-compatible)
• Updates library dependencies to the relevant master branches
• (As was done in the core organization) updates to use GitHub Actions for CI

It also takes an extra step to make the publishing process smooth for you once your dependencies have published their official releases, notably:

• Updates the Bower link to match the URL in the purescript registry, which is necessary when you go to release a new version.

---

When PureScript 0.14 is released, then you'll still have to make a new release of this library; luckily, if this PR is already merged then you'll only need to take these steps:

1. Update your Bower file to point to the new major versions of your dependencies, instead of master
2. Commit and tag a new major version of this library
3. (Optionally) publish the new documentation to Pursuit with pulp publish

I can circle back when we've released new versions of your dependencies. Once you've made a release of your own, then I can update the relevant downstream libraries and make sure that event is up to date in the package set. Please let me know if I can be helpful with any other step!
