Symfony 8 support

Hello, when will the **web-token/jwt-bundle** repository receive the updates that include support for Symfony 8?

The bundle [lexik/LexikJWTAuthenticationBundle](https://github.com/lexik/LexikJWTAuthenticationBundle) is dependent on this update to complete support for Symfony 8; other dependencies are already up to date.
