[what-the-diff]

• Update .editorconfig file
• Add new changes to CHANGELOG.md
• Remove dependency-checker from composer and update README with instructions on how to install the package without --prefer-dist flag
• Change type hints in CurrentRoute, Group, MatchingResult classes from annotations to methods signature (PHP 8)
• Fix some typos in docblocks of RouteCollectorInterface class: add missing return types for middleware() and prependMiddleware() methods; fix wrong param name $middlewaresDefinition -> $middlewareDefinitions; remove @return self annotation as it is redundant since all these functions are returning this object anyway
• Added support for named arguments in middleware methods.
• Fixed duplicate hosts issue (now they are removed).
• Updated RouteNotFoundException message format according PSR-7 standards: https://www.php-fig.org/psr/psr-7/#32-message . Also added unit tests for exception constructor parameters validation logic since there were no such tests before but I found a bug while working on this PR :)
  5`. Improved debug info output formatting + minor fixes here & there...
