MacBook Air m1 processor bus error fixed

So I got Jekyll 4.2 to run natively on my M1 MPB!🎉

I'm not 100% sure I've captured all the steps below that made it work but it should be the most important steps.

Here's what I did:
From: sass/sassc-ruby#146 (comment)
(re)install gems giving arch issues with native extensions
gem uninstall sassc
gem install sassc -- --disable-march-tune-native
gem uninstall ffi
gem install ffi
Update bundler for good measure
bundle update --bundler
Add webrick because otherwise Jekyll won't run on Ruby 3.0 jekyll/jekyll#8523
bundle add webrick
Make sure to rebuild everything. This threw some errors, I had to run this a few times before it worked.
bundle install --redownload
And now:
bundle exec jekyll serve
works! 👍
