👷(github) lint and build code sources

Add a new job that ensure that all code sources
pass ESLint lint rules, Prettier lint rules, and we
can build the static output from code sources.

It makes sure we maintain a high code quality,
and that merging code into the main branch
won't result in error in Scalingo deployment.
