Fix callable phpdoc for twig elements

[VincentLanglet]

Hi @fabpot

[MyRuntime::class, 'myMethod]

is not a valid callable in PHP 8 https://3v4l.org/tWqPs

But this syntax is supported because twig has a special behavior

$compiler->raw(sprintf('$this->env->getRuntime(\'%s\')->%s', $callable[0], $callable[1]));

The PHPDoc should be updated in order to reflect the real behavior and solve static analysis errors.
A phpstan discussion can be found here: phpstan/phpstan#9567

Maybe that's something we want to deprecate?

@fabpot Isn't it a requirement for lazy loading?

Why would we want to deprecate it ? this is what supports the runtime feature, enabling lazy-loading.

Are you sure is a class-string and not a service id?

[fabpot]

Thank you @VincentLanglet.

Yes @jordisala1991, the signature is
´´´
public function getRuntime(string $class)
´´´

@fabpot Thanks for the merge.

Currently, all phpstan-bleeding-edge users will have static analysis build failing since this PR is currently not release.
I was wondering what is the twig planning for release, and if it was possible to make a patch release of twig 3.x if none was planned soon. Thanks :)

Sorry for the delay @VincentLanglet; this one fell through the cracks. I've just made a new release.
