Add github action to run checks on push and pr to main

[n-peugnet]

Once this is merged, composer check will be run on each push to main and each pull request targeting main.

Errors to fix before the CI can pass

Fix composer.json

You can check that it is correct using composer validate. To fix it you will first have to add these two fields:

• name : The property name is required
• description : The property description is required

You should also fix the license field to reflect the current license: AGPL-3.0-or-later

Then run composer update --lock to update the lockfile and get rid of the following error:

The lock file is not up to date with the latest changes in composer.json

Fix the last phpcs errors

composer fix
