Incorrect documentation for network access in plugin manifest

In the intro paragraph, the example given for the plugin manifest is invalid. The valid value for “allowedDomains” is ["none"], not "none". Additionally, "devAllowedDomains" cannot be set to "none" as validation complains that “none” is not a valid url.
