As far as I know, Virtual Threads is a new feature introduced after JDK 21, and Spring Boot added support for it starting from version 3.2. Should we add this configuration in dubbo-spring-boot-3?

but we don‘t have dubbo-spring-boot-3,only have dubbo-spring-boot-3-autoconfigure,but spring-boot-3-autoconfigure mainly handles aspects related to the Triple protocol, which is not closely related to configuration. Moreover, all configuration is processed in DubboDefaultPropertiesEnvironmentPostProcessor.java. Additionally, I believe that if the user is not using JDK 21 and Spring Boot 3, they wouldn't enable this configuration anyway.@Stellar1999

I think it's pretty simple at the moment, consider refactoring and pulling it out later when there's more configurations,
