Update Ruby Fusion as Alchemists

[bkuhlmann]

Why

Hello. 👋 I'd like to retire my Ruby Fusion meetup in favor of my Alchemists meetup. The meetup will still be focused on Ruby, first and foremost, while also teaching and entrepreneurship in the Ruby space. This allows me to host events with a Ruby focus, as the base, but with potential to have other discussions that might be a bit more beyond Ruby.

Notes

If there is any more information you need to update (like beyond the URL), let me know. Happy to provide. Thanks. 🙇
