Introduce phpstan todoby

I started implementing it by I need to fix some things in their rules (like our own deprecations are not correctly calculated on dev versions)

```
	todo_by:
		referenceVersion: "nextMinor"
		ticket:
			enabled: true
			tracker: github
			github:
				defaultOwner: api-platform
				defaultRepo: core
				# credentials:  %env.COMPOSER_TOKEN%
```

```
composer req --dev staabm/phpstan-todo-by:^0.3
```
