Fixes: #11551
* chore(build): WIP getting ionic working with app-scripts
the tsconfig file change is just for testing, this will need to be
undone
* chore(demos): update tsconfig and gitignore for demos
update tsconfig and gitinogre for demos
* chore(build): WIP check in progress with building with app-scripts
this only works with demos/action-sheet currently
* refactor(demos): add custom copy config
add custom copy config
* chore(tsconfig): revert root tsconfig
* chore(demos): change import paths
* chore(demos): move sass config, add new tsconfig, update template
* chore(scripts): update demos tasks to use app scripts with folder name
tweak the createTempTsConfig function to include a path to read from,
move getFolderInfo into util to share
at this point you should be able to run `gulp demos.prod` with a folder
e.g. `--f=alert` and open the index of that test to see it. Doesn’t
work yet with all of the tests at once. Need to have ran `gulp
release.prepareReleasePackage` first.
* chore(build): WIP working on getting all of the demos building
* chore(demos): update demos task for app-scripts build
* chore(demos): fix tslint errors thrown by app-scripts
* chore(demos): get the demos working with fonts and variable file
