Tests: add Requires* attributes

PHPUnit 10 introduced attributes as replacements for docblock annotations.
PHPUnit 11 deprecates the use of docblock annotations in favour of attributes.

If both an attribute as well as an annotation are found, no PHPUnit deprecation warning will be thrown.

However, between PHPUnit 10.0 and PHPUnit 11.3.2, if the `failOnDeprecation` is set to `true` (which it is for this library as the builds should fail on deprecations in PHP), builds will _also_ fail on deprecation notices from PHPUnit itself.

This behaviour was (finally) changed in PHPUnit 10.5.32 and 11.3.3 (released this week), but that's insufficient for our needs.
For this library running the tests on high/low PHPUnit on each PHP version is imperative. It is also not the job of this library to decide the target PHPUnit versions for the consumer projects, so we cannot raise the minimum PHPUnit 11 version to 11.3.3.

This means that without the attributes, the test runs for the package would fail on PHPUnit 11.0.0 - 11.3.2.

As these attributes are already available in PHPUnit 10, it makes sense then to add them for both the 2.x branch, as well as the (upcoming) 3.x branch.

This commit adds the `Requires*` attributes in all the appropriate places.

The `@requires` annotations remain as the tests also still need to run on PHP 5.6 - 8.0 using PHPUnit 5.x - 9.x.
These can be removed once the codebase has a PHP 8.1/PHPUnit 10 minimum requirement.

Note: due to the syntax for attributes, these can be safely added as they are ignored as comments on PHP < 8.0.
Along the same line, if there is no "listener" for the attributes (PHP 8.0/PHPUnit 9.x), they are ignored by PHP as well.
