Status update

Everything is ready for merging; we have dynamically updating sections: past, upcoming and in progress events will each have their own section.

I have extracted out the data from the current events page into a Go script that I will use to batch post the events instead of me manually making multiple transactions. You can see the events data up to the most recent ones here. This is how it will look like on gnoweb:

@moul, can you please take a look at the event data and confirm everything looks good, and I will go ahead with the merge & posting of events to Portal Loop? 🙏

P.S. sorry for the weird screenshot, gnoweb does not like to cooperate

Merging as @moul is OOO, the data in the realm is already public, and we have the ability to edit/delete anything we see fit.
