fix: remove run-sequence from gulp `deploy:dist` task to detect its end

`run-sequence` doesn't match well with multile streams from `gulp-filter` and prevent us to use the stream end event or gulp to automatically detect the stream end. This commit refactor the `deploy:dist` task and move its logics to `deploy:dist:files` in order to make gulp dealing directly with the `gulp-filter` stream and detect its end.
