Fixes #3979 sentinel-feign.FeignException$InternalServerError #3979

Describe how you did it

enable spring.cloud.openfeign.circuitbreaker.enabled

Describe how to verify it

1. git clone https://github.com/alibaba/spring-cloud-alibaba -b 2023.x
2. open spring-cloud-alibaba-examples/sentinel-example/sentinel-circuitbreaker-example
3. enable spring.cloud.openfeign.circuitbreaker.enabled
4. access this endpoint http://localhost/test/default/false , it should return user fallback

Special notes for reviews

Maybe we should shade starter spring-cloud-circuitbreaker-sentinel, toggle state with spring.cloud.circuitbreaker.sentinel.enabled

By the way, I found that many projects which based on spring-boot 3.x or spring-web 6.x, required jdk17+ and Jakarta. It affect many Sentinel releated projects ,eg alibabaspring-cloud-alibaba、alibaba/Sentinel and sentinel-group/sentinel-website and alibaba/Sentinel.wiki, maybe we should archived some project and write more test case (blockHandler) for other modules to improve quality.
