[refactor] Update to advanced asset pipeline

[lesm]

The goal of this task is to be able to update middleman, currently we're using middleman 4.2.1 (2017)

Middleman removed the Rails asset pipeline (middleman-sprockets) in his version 4.4

• Remove middleman-sprockets gem
• Serve the assets from the new advanced asset pipeline
