Update Github Actions

[franmomu]

This is what I would do, but that's based on other setups and personal preference, so feel free to pick up whatever you want or nothing 😄

The changes:

• Extract composer validation to another job (there is no need to install dependencies) and also normalize composer.
• Extract Static Analysis to another job to simplify things.
• In the test job, use ramsey/composer-install@v2 to install dependencies and do not use the external sh file.

I would also add a job and use a tool for coding standard issues like https://github.com/PHP-CS-Fixer/PHP-CS-Fixer or https://github.com/squizlabs/PHP_CodeSniffer

Oh no, my good old install_dependencies.sh script is gone. 😂 I further simplified things and did some changes due to my personal preference (as you already named it). 😉

What do you think?

Well, a CS fixer could be added in a next step, but first things first.

It looks perfect now and will be the blueprint for my other repositories. Thank you, @franmomu.
