Okay, I managed to confirm the previous existence of this festival. I found an independent source about the 06 event, which I added as a reference. Problem is, I can't confirm the CURRENT existence! So I've changed to past tense, and eliminated the "recurring event" infobox. I don't see any truly original research, and there are citations here... so I also removed the tags.
The official website looks defunct. I can't yet find anything discussing the dissolution of the festival! In fact, I found tour guide-y sites that advertised the 2023 and 2024 version, but with no active link or date or any evidence of actual existence. If you find this info, please add it back!
