Added compatibility with PHP 8.1

[andrewbess]

Hello @tomzx

We still have problems with class \PHPSemVerChecker\Report\Report.
The problem looks like showed below when I run phpunit

During inheritance of ArrayAccess: Uncaught PHPUnit\Framework\Exception: Deprecated: Return type of PHPSemVerChecker\Report\Report::offsetExists($offset) should either be compatible with ArrayAccess::offsetExists(mixed $offset): bool, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /Users/andrewbess/work/projects/my-project/vendor/tomzx/php-semver-checker/src/PHPSemVerChecker/Report/Report.php:161

We should add attribute #[\ReturnTypeWillChange] above methods offsetExists, offsetGet, offsetSet, offsetUnset, getIterator or we should add return types (that is not BIC) because the return types have been added there in PHP >= 8.0.

This pull request provides the fixes for the class \PHPSemVerChecker\Report\Report according to php.net ArrayAccess interface and php.net IteratorAggregate interface. Also, we fixed error reporting in src/PHPSemVerChecker/Console/Application.php.
Finally, we checked these changes in PHP 7.4, 8.0, 8.1. It works well.

Cloud you please check it?

Thank you in advance.

Hello @andrewbess, just to confirm, this is not a blocking issue? I'm asking because the unit tests did not point to an issue and if there is, I'd like to add a test to prevent further errors.

Hello @tomzx
Thank you for the fast reaction here.
This is priority issue for me, we cannot release our project.
However this is not blocker.

I will try to add test here.

Thank you in advance.

Hello @tomzx

Hello @tomzx
We've fixed our pull request.
The latest changes provide compatibility with PHP 8.1, while at the same time they provide backward compatibility for 3-rd party extensions.
The using the attribute #[\ReturnTypeWillChange] provides this possibility.
Also, could you please process this PR? The problem is critical for us.
Thank you in advance.

Hi @tomzx
Please note that while this suppress E_DEPRECATED in "standalone" application there are still deprecation messages generated if this module is used as dependency. Would be great if this PR could be merged and new version released so that issue resolved everywhere

Hello, I've removed the error silencing in v0.15.0. Let me know if this fixed your issue.

@andrewbess Hello @andrewbess, I've updated the code with changes that are mostly similar to what you suggested in your PR (I've opted to use void and bool where appropriate instead of #[\ReturnTypeWillChange] and only used it for ``mixed` which becomes available in PHP 8.0.

Let me know if you're still facing issue (either by reopening this issue or creating a new one).
