Use 8.4 compatible "safe" library and move to require-dev

Activity again in the original repo, @shish got access.

Ill commit this since its a change to dev, Ill switch back to coding machine later.

I figured out the problem with CI, looks like theres a difference where code lies when ran as a fork. In your MR, the composer step is failing despite it being green.

My green MR @ https://git.drupalcode.org/project/pinto/-/merge_requests/16 with the same code as yours. Ill close this one and commit yours since I know it works.

v0.2.2
