Proven reusable workflows
Added
- php-composer-dependencies-reusable.yml: Test composer dependencies, PHPUnit tests and PHPStan check
- overtrue-phplint.yml: Basic PHP linter
- linter.yml: Super-Linter of many formats
- Automatic PHP improvements: phpcbf.yml
Fixed
- added .shfmt configuration for super-linter but VALIDATE_SHELL_SHFMT: false is the only solution, anyway
