removed gaze from dev dependencies and removed not working dev script

[vince1995]

There was a dev script added in 18f9e5340563833cebab333ee6205d5c8ac6413a where gaze was added to the dev dependencies and a script named dev was created in the package.json.

The dev script was removed in 021a12f648d53b30392f4ca3d4e3a78bebab1f54 but the package.json wasn't cleaned up. Instead gaze was updated several times. 🤔

This PR removes the gaze package from the dev deps and removes the dev script from the package.json.

Good catch! Can you update package-lock.json?

Done. 👍
