Symfony deprecations in Constraint plugins

Problem/Motivation

In #3420990: Convert Constraint plugin discovery to attributes, the conversion from using annotations to attributes for Constraint plugins led to tests failing because Symfony deprecation warnings like these:

These warnings were either suppressed or addressed with @return annotations. This is a follow up to address the deprecations:

• Add method typehints. See #3233482: [Symfony 6] Add type hints to methods overriding Symfony\Component\Validator\Constraint::getDefaultOption() and ::getRequiredOptions()
• Stop overriding Symfony class properties. See #3276196: The "Symfony\Component\Validator\Constraints\Range::$minMessage" property is considered final
• Remove suppressions in .deprecation-ignore.txt
