fix: remove @internal annotation from orderColumn() method

The orderColumn() method in QueryDataTable is documented and intended
for public use (as shown in package docs), but was incorrectly marked
as @internal. This caused static analyzers like PHPStan to report false
positives when calling the method in userland code.

Removing the @internal annotation clarifies that orderColumn() is part
of the public API.
