Specify expiry time in confirmation view

[djk20]

Feature request.
It would be nice if src/templates/ConfirmationView.ts specified the expiry time for the content, perhaps something like:
After the expiry time (Sat Nov 12 03:27:33 UTC 2022) is reached, the content will no longer be available.
or
After the expiry time (1 day) is reached, the content will no longer be available.

That's a good idea, it should be possible to do it by passing ttl into

one-time-secret/src/WebControllers/ConfirmationController.ts

Line 43 in 81f0919

response.end(this.render(secretUrl.toString()));
