Add PHP8 attributes for our existing service annotations

[aschempp]

Replaces terminal42/service-annotation-bundle#6

The new naming follows the Symfony convention

These attribute names follow the pattern #[As...]. Symfony 5.3 provides #[AsCommand] to define a PHP class as a Symfony console command, #[AsEventListener] to define a PHP class as a Symfony event listener, etc.

Can you give an example of how to use the new feature?

[aschempp]

// register hook
#[AsHook("outputFrontendPage")]

// registering two hooks for different methods
#[AsHook("outputFrontendPage", method: "foo")]
#[AsHook("parseTemplate", method: "bar")]

// register content element
#[AsContentElement(category: "texts")]
#[AsContentElement("my_type", category: "texts")]

Using named arguments you can skip the optional arguments 😊
Unfortunately, Symfonys service attributes are not supported on methods, but the same can be done through the method argument.

Maybe I am missing something but the constructor arguments do not match the annotations in the ServiceAnnotation namespace, do they? E. g.

// AsContentElement
string $type = null,
string $category,
string $template = null,
string $method = null,
string $renderer = null,
array ...$attributes

// ContentElement
@Attributes({
    @Attribute("value", type = "string"),
    @Attribute("category", required = true, type = "string"),
    @Attribute("template", type = "string"),
    @Attribute("renderer", type = "string"),
    @Attribute("attributes", type = "array"),
})

Is this correct?

Edit: As discussed with @aschempp, this is correct. The value attribute corresponds to the $type property and the $method property is used to assign the attribute to a method, because
