Validation satisfies() `config` argument is not documented

Validation `satisfies` `config` parameter is not documented. Should be something to the effect:

>The optional `config` parameter is an object that will be included in the context available to formatted validation messages. For example: the default `maxLength` validation message uses the config object like this:
>
>`"${$displayName} cannot be longer than ${$config.length} character${$config.length === 1 ? '' : 's'}.`

Note that `customRule` documents it this way:

>The config object is used when computing the validation message when an error occurs, enabling the message expression to access the rule's configuration.
