chore: upgrade PHPUnit 9 => 10

[Chris53897]

changes for sebastian/comparator

#746 rebased against master.
Migrate Config PHPUnit 9 => 10
Only Allow PHPUnit 10.

I did not have a closer look to the comperator changes.

Tests are failing, because of
DeprecatedMethod: The method PHPUnit\Framework\TestCase::setLocale has been marked as deprecated (see https://psalm.dev/001)

[Chris53897]

I replaced it with direct calls to setlocale().
But i am not sure if this is enough.

This looks good. Only with regard to setlocale I would solve that differently

[frederikbosch]

I would add a file called tests/LocaleTest.php, with the following content.

declare(strict_types=1);

namespace Tests\Money;

trait LocaleTest
{
    public static function setLocale(int $category, string $locale, \Closure $callback)
    {
        $currentLocale= \setlocale($category, 0);
        try {
            \setlocale($category, $locale);
            $callback();
        } finally {
            \setlocale($category, $currentLocale);
        }
    }
}

And then remove setlocale from setUp but simply use it in the test file as follows

use Tests\Money\LocaleTest;

public static function the_test()
{
    LocaleTest::setLocale(LC_ALL, 'ru_RU.UTF-8', function () {
        // test content here
    });
}

I followed your suggestion. But i did need to make some changes to make it work.
The name setLocale is already taken with other parameters.

Filename changed from LocaleTest to Locale

I am not sure if i did everythink correct. Please have a look.
