Bump minimum PHP version to 8.1

[kamil-tekiela]

The code uses the never type which was introduced in PHP 8.1 so we need to bump the minimum version.

Bumping the version is okay for me, but an alternative could be to remove the never return type (could be an annotation instead).

And we should probably use some tooling which can detect such issues.

PHP 8.1 is pretty old by now so I feel dropping the support is better. If I find something from PHP 8.2, I will do that.

FYI: All the PHP servers should run PHP 8.2, so don't go using 8.3 features yet :-)
