Support for full PHPUnit public API

[ghost]

Closes #6

• Support for full PHPUnit public API
• Optimized readability and maintainability of the code
• Organized the tests of the asserts in alphabetical order and according to their source
• Updated all docs about asserts

@Naktibalda Can you please take a look here and there.
It would be great if the changes were merged there to test through the CI here 👍 .

Cool, thank you for refactoring this part!
Could you look into failing tests?

Unit Tests (10) --------------------------------------------
PHP Fatal error:  The modifiers of the trait method assertClassHasAttribute() are changed, but this method does not exist. Error in /home/runner/work/module-asserts/module-asserts/src/Codeception/Module/AbstractAsserts.php on line 8

Thank you!

@DavertMik The tests are failing because Codeception Module Asserts does not support various asserts from the public phpunit API, including the one that appears in that error, I presented a PR to add a large number of asserts that are not available so far, and since this repository uses that library, the CI server will fail until the changes are made merged first there.

Thank you!

Composer command in Github Actions fails because it takes too long.
@TavoNiievez Please make this change #8 in your branch.

[Naktibalda]

I will fix it myself.
