Sylius: Replace gulp with Webpack (encore)

[jelen07]

:wave: Hi guys! At the moment Sylius using gulp for building assets - admin and shop.
Our feature request is replacing the gulp process with webpack encore.

The installation will be the same as now

$ yarn install
$ yarn build

Todo

• rewrite the build using webpack for admin and
• shop
• remove gulp from project
• [optional] rewrite Sylius JavaScripts for webpack (frontend JS is in a deplorable state)

Profit

• One modern build tool (when using Sylius/BootstrapTheme you have two build tools in your project)
• Consistency
• Get rid of deprecated errors
• Sylius will switch to Bootstrap anyway

@jelen07 there is still some work to be done, but we have already started testing the encore with the sylius-standard https://github.com/Sylius/Sylius-Standard/pull/354

this should be reopen, as the replacement of Gulp with Webpack is not complete yet.

issues I bumped into:

• the package.json file still uses Gulp by default for running various commands (especially from docker)
• docker files should be updated to avoid copying Gulp files and copy webpack instead

How do we do to be able to use that?
