chore: remove scripts from composer.json

[mcdurdin]

Ah, I added the one in composer.json in #389 for feature parity with help.keyman.com

Hmm, so we should probably remove from all then. Let's keep composer.json minimal, remove all scripts, seeing as we do them in ci.yml now?

I see we never call composer run test either, which means we should probably add vendor/bin/phpunit --testdox to ci.yml and/or Dockerfile?

How do we run lint and phpunit tests locally?

1. Remove the scripts from composer.json
2. Make it possible to lint and phpunit test from local dev machine
3. Consolidate ci.yml and build.sh test calls (ci.yml should be able to call build.sh?)

This should also be done on help.keyman.com, elsewhere as well?

I thought one of the intents of putting everything into Docker is that the dev environment doesn't need to install anything else (Composer, PHP, phpunit, etc)

Yeah, but we still need to be able to trigger them, even if they run in the container, right? How do we do that?
