Alert URL missing from alert in TransitLeg

[landonreed]

When displaying an itinerary with alerts, the expanded alert does not render the alert URL. This prevents directing users of the trip planner to more information about the alert that may be contained on the agency website, which is especially useful if it contains dynamic or detailed instructions.

Instead, we should add the URL with the hyperlinked More text

From @fpurcell:

Dave, Noel & Jonathan (the Mkt. folks) want something similar.
For the trimet.org redesign, here are the mockups around the itin and the alert link. https://xd.adobe.com/view/cef25753-fbd1-4e9d-7bf1-c5bc3bff8219-b8c3/screen/867915f3-2160-4c66-8f92-01fde40bdbeb/Planner-Itinerary

Noel writes (comments surrounding that mock up): "Clicking the alert will take you to that service's alerts page." (edited)

So yes. I think a slot with customizable control would be best. But in the interim, if alerts all of a sudden start opening an alert page, that would work. That said, I would think (e.g., open the alert page in a new tab) would be important, since don't want an alert link to pull folks out of the trimet.org SPA.

FYI .. response from Randolph regarding alerts and otp-ui:

As seen on the current dev branch (of trimet.org), the linking of alerts is done through the AlertsBody component being invoked from within the default TransitLegBody in OTP-UI. We haven't modified it and I assume that making this customizeable is the topic of conversation? Josiah and Matherin and working on customizing the trimet.org itinerary view as we speak (customizing the itinerary body using those new slots). If we can customize via a slot then great. Otherwise, yes, having the ability to customize the target to _blank would be very helpful.
