[WIKI] Dead vimeo link

[AlexanderHott]

The "Scott Wlaschin — Railway oriented programming" vimeo link is dead in this wiki page https://github.com/supermacro/neverthrow/wiki/Railway-Oriented-Programming-(1hour-video).

I believe this is the same video on YouTube, but I'm not 100% sure. www.youtube.com/watch?v=fYo3LN9Vf_M

I also don't know how to edit the wiki, I couldn't find a way to submit a PR for it.
