Add styleguide/ as submodule

This should make new contributors aware that the Styleguide exists and
maybe maybe even encourage people to contribute to the Styleguide.

Also this enabled `yarn run dev:styleguide` to build the `webapp/` along
with the styleguide.

Issues

• None

Todo

• If we decide to merge this PR, we should setup dependabot to automatically update the submodule. The policy should be to automatically merge a new commit of the submodule, because it's the same team that reviews PRs in this repo as well in this repo.

Looks fine to me. As far as I can say. @roschaefer

Do you have spoken with @appinteractive about this?
