Xdebug Now Supports PHP 8.5

Other packages have also added support, so we can now switch to 8.5.

Version constraints are unnecessary for regular Composer packages, except for those like Xdebug where version updates have significant impact.
Just specify ^8.2 and add constraints only when you find it doesn't work with a new version under development.
If the compatibility work only involves modifying composer.json, the constraint is meaningless.
