TBD: events page

[dholbach]

@vanessaabankwah suggested we create an events page, where we list upcoming and past events that happened.

Let's discuss how that could look and how we'd use it.

We should try to make this integrated with https://fluxcd.io/#calendar – we obviously can't list 100% of flux-related events there, but we should make sure these events all get pulled in so we don't have to repeat them 👍

This also doesn't handle past events in its current form, that seems like a useful idea!
