Support "-parameters" java compiler arg in vscode-tools

[bclozel]

As of Spring Framework 6.1, Spring applications now need to be compiled with the "-parameters" Java compiler argument. This is now required for many Spring features - most annotation-based programming models in Spring need to read the names of method parameters.

For example, this Spring MVC controller will not work anymore if this compiler argument is not set:

@RestController
public class TestController {

  @GetMapping("/user/{id}")
  public User findUser(@PathVariable Long id) {
    //...
  }

}

Many guides on Spring academy will work when run with ./gradlew bootRun but won't if the user runs the application from VSCode. I've found that this compiler argument can be turned on by adding a JDT compiler configuration file.

Could you update the VSCode image to include this by default?

Pinging @robertmcnees on this issue since we encountered this problem while working on the Spring for GraphQL guide for Spring Academy.

Thanks @bclozel we should be able to overlay the necessary configuration into the Academies editor configuration. We'll give a go and report back here.
