• Added PHP 8.4;
• Updated squizlabs/php_codesniffer to use the new repository;

[gsteel]

There are PHP deprecations getting emitted during tests:

https://github.com/laminas/laminas-xml/actions/runs/11254698819/job/31292696978?pr=19#step:3:380

These will need to be fixed (and PHPUnit should be configured to failOnDeprecation)

There are 4 implicit null arguments by the look of it

@gsteel Unfortunately the optional parameter order is deprecated as well https://github.com/laminas/laminas-xml/actions/runs/11274526733/job/31353887275?pr=19#step:3:231

@SuperDJ If you could trim trailing whitespace in the readme and fix the min PHPunit version, we should have green CI

Thanks for sticking with it!
