[Codecept5] Improved support for Codeception 5/PHP 8

[yesdevnull]

I need to do the following:

• Consolidate Symfony version requirements compared to Codeception 5 (e.g. supported PHP versions).
  Symfony 4.4 and 5.4 are LTS versions so are updated to support the latest PHP versions.

• Fix codeception/codeception version requirement.

• Fix codeception/lib-innerbrowser version requirement.

• Add several basic smoke tests?

• Correct commit message to be consistent with repository.

Bonus points (for a separate PR maybe):

• PHPStan (using config from module-doctrine2)

I normalised composer.json using ergebnis/composer-normalize. I like the consistency of a normalised composer.json but happy to revert if you'd prefer it to be kept as-is.

@yesdevnull The next thing to do is to update lib-innerbrower to be compatible with the changes from Codeception/dev-5.0-interfaces.

This module doesn't support Symfony 6 yet... although i already added the corresponding branch in the test project https://github.com/codeception/symfony-module-tests/tree/6.0 .

Which leads me to say that we don't need smoke tests as we do have tests for this. Please check the aforementioned codeception-module-tests, maybe it should be mentioned in the README.md that we have the tests in another repository.
It can help you understand how it works by reading the main.yml file and maybe CONTRIBUTING.md

I'm a big fan of all the initiatives to 'normalize', 'update' and 'standardize', so I support you on the topic of normalizing the composer.json file.
The only thing is that since this is normalization, it would only make sense if all of Codeception uses the same normalized style. So I would ask you to raise PR to update that in all of our repositories if you want to go ahead.

Lastly, regarding PHPStan, yes please!
A separate PR would be nice.

dev-5.0-interfaces branch is gone, you can set codeception/codeception to ^5.0.0-alpha2 and lib-innerbrowser to ^3.0.
