Document that active profiles are set at build time with AOT

[luooyii]

I'm not sure if this is a bug.

I am using Spring Boot 3.2.3 and GraalVM CE 21.
Here are the context in application.yaml and yaml files under resources folder.

spring:
  profiles:
    active: local

If I startup the service jar file with cmd "java -jar app.jar --spring.profiles.active=cluster". Activation item will be overridden and only one profile is actived. Here is the spring output log.
2024-03-21 01:01:23.325 [main][0;39m - The following 1 profile is active: "cluster"

But if I use graalvm native image to compile the service and startup AOT package with the same param, just like "./app --spring.profiles.active=cluster". Both "local" and "cluster" will be activated. Here is the spring output.
2024-03-26 15:29:23.448 [main][0;39m - The following 2 profiles are active: "cluster", "local"

Thanks for your reply. Here is the minimal sample https://github.com/luooyii/BugDemo
Reproduce steps:

1. Clone the code
2. Run cmd 'mvn clean package'
3. cd target
4. Run cmd '.\native.exe --spring.profiles.active=cluster'
5. You can see output, the new param is accepted but the default value is not overwritten. And if we run the app using jar file with the same param, only "cluster" will be activated.

I think this is because of #30421.

As mentioned by Moritz, this is by design. I haven’t seen a specific mention of that in our AOT reference docs so let’s turn this into a documentation isssue.
