RFC: Pretalx schedule exports

[glasnt]

As we host pretalx infra, we generally allow -- if not encourage -- embedding schedules from pretalx itself.

After an event is complete, the schedule is no longer in flux, and should be migrated to a static form to the website.

There could be an export script that allows an authorised person (doesn't have to be from the event, but probably shouldn't be an external contributor) to export a devopsdays-schedule-appropriate static schedule to be added to the website.

I have personally previously played with the automation available with pretalx and have some scripts, but others may also have this. From memory it requires access to the event instance, which may be a larger question.

I had the idea to create a system that generates a PR from Pretalx to DoD website
The idea was to have a Pretalx plugin that would run when you release a schedule and send a webhook to another system that generates the necessary setup.
I wrote the webhook part called ConfereceHook, and we did use it for DoD Antwerp.
Here are some examples of PR's generated by the webhook

• [ANTWERP-2024] Pretalx => DoD Schedule Auto Update devopsdays-web#14540
• [ANTWERP-2024] Pretalx => DoD Schedule Auto Update devopsdays-web#14314
  I never got around to creating the Pretalx plugin, and this is why it isn't being used for now
