chore(docs): Add description of consumer version selectors to the documentation.

BREAKING CHANGE: The type for consumer version selectors in the verifier has been corrected. This will affect typescript users who were using consumerVersionSelectors with the fields `pacticipant`, `all` or `version`. These fields never worked, and now will no longer compile in typescript. The correct type is:

```
ConsumerVersionSelector {
  tag?: string;
  latest?: boolean;
  consumer?: string;
  fallbackTag?: string;
}
```

Note that `pacticipant`, `version` and `all` have been removed. Existing code that uses `pacticipant` needs to use `consumer` instead. The other fields can be dropped. Any questions, please reach out to us at https://slack.pact.io/
