build: add :soto, always install dependencies [ci skip]
Ensures that the JS associated with :soto is built when running `make
interface`.
Additionally, adding `npm install` as a mandatory step for all Landscape
builds goes some way towards resolving though it's not a complete
fix.

cd pkg/interface/chat
