fix: generate typings directly in lib instead of lib/src

[elevatebart]

in version 11.1.5 when we moved to Github Actions we added a dangerfile.ts to the tsconfig.json
This file, since it is outside the src folder, changed the reference rootFolder for typings to calculate.
This quick adjustment should fix the typings.

I also updated CI to have clearer action steps (where we can measure progress from a high level).
Cypress 3.0.2 does not seem to work well with the Linux version on the github action docker images.
