Resolve the following deprecation when running the test suite with PHP 8.3:

    Remaining self deprecation notices (1)
      1x: Calling ReflectionProperty::setValue() with a single argument is deprecated
        1x in SemverTest::testUsortShouldInitialVersionParserClass from Composer\Semver

Reasons:
- consistency: some data providers were already static, now all of them are static
- performance: the class does not need to be instantiated anymore to execute the data provider
- future-proof: non-static data providers are deprecated in PHPUnit 10

* Avoid mandatory `void` return type of the inherited `setUp` method in PHPUnit 10

This is done by renaming the inherited `setUp` method to a new `setUpTestCase` method and adding an `@before` annotation.

* Use `onlyMethods` instead of `setMethods` on MockBuilder instance when available

This resolves the following error when running the test suite using PHPUnit 10:

    Call to undefined method PHPUnit\Framework\MockObject\MockBuilder::setMethods()
