fixes https://github.com/TryGhost/Ghost/issues/13832 The `date` handlebars helper has only one option currently — `format`. It assumes the locale and timezone from the `options.data.site` object which is not always desired behavior. The helper sometimes is used, for example, in custom RSS template where we always need the `en-US` locale, not the one that we have configured for the website globally. This change makes the two options configurable, and defaults to the `options.data.site` object values, if not specified in the helper (keeps the backwards compatibility with the current behavior).
