feat(manifest): on publish removes devDependencies & scripts (#905)

## Description

- on publish removes devDependencies, scripts and other stuff not
necessary to have for runtime dependency-cruiser usage
- also on publish: adds a dummy 'test' script with a message to run
tests etcetera on the ci (and so socket.dev doesn't shows its bogus
warning about missing tests, which shouldn't be on npmjs in the first
place)

## Motivation and Context

- Makes the published package ~10kb smaller

## How Has This Been Tested?

- [x] green ci
- [x] local publish
- [x] publish on npmjs (see
https://www.npmjs.com/package/dependency-cruiser/v/16.1.0-beta-1?activeTab=code),
install as a devDependency on state-machine-cat and run it

## Types of changes

- [ ] Bug fix (non-breaking change which fixes an issue)
- [ ] Documentation only change
- [ ] Refactor (non-breaking change which fixes an issue without
changing functionality)
- [x] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
