[TASK] Ensure working codeception tests with TYPO3 v13

[sbuerk]

• [TASK] Adjust typo3/testing-framework constraint
  The composer package version constraint for the
  typo3/testing-framework is adjusted to ensure
  latest version for each required major versions.

  Used command(s):

  composer require --dev --no-update \
    'typo3/testing-framework':'^7.1.1 || ^8.2.7'

• [TASK] Remove providing backend entrypoint for TYPO3 v13 in test instance
  TYPO3 v13.0 dropped the backend entrypoint (./typo3/index.php)
  and made the main entrypoint (./index.php) capable of handling
  frontend and backend web requests to make the backend entrypoint
  finally configurable and required to change the rewrite rules for
  webservers to ensure backend requests hits the main entrypoint.

  The acceptance setup for b13/container is based on the TYPO3
  monorepo setup using a real Apache2 webserver instead of the
  PHP internal webserver and thus needs .htaccess rules to work.

  Providing needed .htaccess files has been added to the TYPO3
  monorepo only and broke the setup for acceptance testing against
  TYPO3 v13. As a workaround providing the old backend entrypoint
  file has been implemented within the extended codeception setup
  method BackendContainerEnvironment::bootstrapTypo3Environment()
  which worked but is literally wrong.

  typo3/testing-framework now provides these files automatically,
  and the wrong workaround can be removed to cleanup the code base
  [1][2][3][4] and is backwards compatible for older TYPO3 versions.

  Some phpstan ignore pattern can be now removed from baselines and
  is done in the same run.

• [TASK] Use composer package names for acceptance extension configuration
  typo3/testing-framework allows to use composer package names
  instead of classic mode references as extension to load for
  functional and codeception acceptance test instance creation.

  Use composer package names for acceptance test extensions to
  load now.

• [TASK] Adopt codeception helper login page check from testing-framework
  For the codeception acceptance tests a custom codeception helper
  is used to verify the login state, using /typo3/index.php to
  check for backend login mask page.

  Using the full endpoint is not reasonable and breaks with TYPO3
  v13.0 and newer which removed that endpoint completly and this
  change modifes the check to use /typo3 path instead, adopting
  from provided typo3/testing-framework helper which is fully
  backwards compatible.

• [TASK] Use apache2 and PHP-FPM for acceptance tests for TYPO3 v13
  TYPO3 Core development switched codeception based acceptance
  testing using apache2 and PHP-FPM instead if the internal
  PHP cli webserver due to rewrite rules required to operate
  TYPO3 properly, special with removed backend entrypoint since
  TYPO3 v13.

  This change adopts required changes within Build/Scripts/runTests.sh
  to make the switch and be in line with core development regarding
  acceptance testing for TYPO3 v13 only, keeping the PHP internal
  webserver for older TYPO3 core and testing-framework versions.
