	 * Provide a modified UA string to workaround web properties which block WordPress "Pingbacks".
	 * Why? The UA string used for pingback requests contains `WordPress/` which is very similar
	 * to that used as the default UA string by the WP HTTP API. Therefore requests from this
	 * REST endpoint are being unintentionally blocked as they are misidentified as pingback requests.
	 * By slightly modifying the UA string, but still retaining the "WordPress" identification (via "WP")
	 * we are able to work around this issue.
	 * Example UA string: `WP-URLDetails/5.9-alpha-51389 (+http://localhost:8888)`.
