## What is the purpose of this PR?

There was a noticeable startup time when generating a widget using `npx
@mendix/generator-widget`. This was due to the bin script installing
yeoman and the generator globally each time.

## Relevant changes

- The generator is run using `yeoman-environment` (which the `yo` cli
tool is a wrapper for).
- Dependencies with vulnerabilities have been patched using `npm audit`

## What should be covered while testing?

Generating a widget using the `bin.js` script.
