expose RIS dump timestamp via API and BGP Preview UI

[nusenu]

It would be really valuable to know, what data we see when looking at the BGP Preview data and UI page.
More specifically:

• From what time is the RIS dump that is being used?

Note: This information has been available in RPKI Validator 2.x as can bee seen here:
http://localcert.ripe.net:8088/bgp-preview ("The RIPE NCC Route Collector information that was last updated X hours and XX minutes ago.")

I'd propose to expose the timestamp of the RIS dumps on ris.ripe.net/dumps (NOT the timestamp when it was fetched from there).

Done in the latest build.

You can see it on the
https://rpki-validator.ripe.net/bgp-preview page
and also it is reflected in the
https://rpki-validator.ripe.net/api/healthcheck/

and also it is reflected in the
https://rpki-validator.ripe.net/api/healthcheck/

should there be a timestamp in the healthcheck response?
