Implement CI/CD #4
Description
User story
As a developer I want to safely commit and ship new code to this repo in an automated way.
How to reproduce the problem
The repository doesn't have yet any CI/CD setup, neither linters or tests, this makes the code and the repositories using our packages unsafe and tedious to maintain.
Describe the solution you'd like
Implement CI/CD with linters and tests.
Acceptance criteria
- There is a test suit for the different packages in the repo
- There is a linter for PHP
- There is a linter for JS
- There is an automated task that runs all of those on each PR (aka, Github Actions)
