Port changes over from berlin.rs

[skade]

There's two changes that could be ported over to the community template:

• The accessibility and the CoC subpages
• Display of accessibility info on the events themselves

This would encourage people to research this info and fill it in.

https://github.com/berlinrs/berlin.rs/pulls?q=is%3Apr+is%3Aclosed+label%3Aport-to-template

The subpages are single pages. You need to clone the Rust meetup template here https://github.com/rust-community/rust-meetup-template and move the general parts of our implementation over.

You can see the changes of a pull request here: https://github.com/berlinrs/berlin.rs/pull/8/files

The info mainly consists of additional fields in _data/locations.yaml and the appropriate display parts.

For the subpages, they just need to be copied. There's some personal info involved, which shouldn't end up in the template. If you want to do a little extra work, try moving them into a _data file.
