feat: added ECDSA-based algorithm support

make the simple-jwt auth0 implementation can use ECDSA-based algorithms

BREAKING CHANGE: the io.jsonwebtoken:jjwt implementation was
discontinued since its design made a big challenge to encapsulation

- * Developers using the Simple JWT library with Spring Boot do not need to

- * However, developers still have the flexibility to customize the behavior of
- * the library by providing their own configurations and properties.
