doc: broken link to Filippo's live coding session

[arl]

Hi,
It seems the link to Fillipo's live coding session of AVO, which is present in the README, is dead.
I've looked for another link to it but I couldn't find it.

Ah yes, it seems to be down.

@FiloSottile Do you think you could revive https://videos.filippo.io, or post the videos elsewhere?

[FiloSottile]

Ah, yeah, that didn't last. I kinda wish some service would take my money to simply host videos at a URL I control. Maybe I should just embed Vimeo into static pages on my site.

[FiloSottile]

Alright, just gave Vimeo some money to host it for me, and gave up on owning the URL.

Should be ready soon at https://vimeo.com/679848853!

I confirm. it's there now, awesome, thanks @FiloSottile

Updated! Thanks for the quick response @FiloSottile :)
