Implement mp4 video provider and add Brighton Ruby 2023 videos

[marcoroth]

This pull request implements a new video_provider for the case where the videos are not hosted on YouTube. In the case of Brighton Ruby they are hosted on their own website.

So this pull request implements a new mp4 video provider, where the video_id is the link to the MP4 file.

Thanks for this great addition.

I think we should ask @andycroll permission first. Organizers who are publishing their videos on Youbute defacto accept that their video can be embedded into another website as it is a native feature of Youtube. Also videos viewed from embedded players do count for the view stats on Youtube.

For orgs having made the choice to host by themself the videos, I think we should get their explicit consent first.

One option could be that we just pull the metadata + Thumbnail and link to the Org website for the player (to be decided by the org)

Good point, I'm more than happy to extract the video provider to its own pull request, since it's technically two "features" in one pull request.

I was just testing the mp4 "provider" with the lastest Brighton Ruby edition, since I knew they were using their own video hosting.

I will send an email to Andy. Don’t change anything for now
