Duplicated server when generating the openapi file in a custom folder

[GersonTf]

Expected Behavior

doing gradle clean build several times should not duplicate the server.

servers:
- url: http://localhost:8080

Actual Behaviour

the server is duplicated in the generated api.yml doc;

servers:
- url: http://localhost:8080
- url: http://localhost:8080

if you keep doing gradle clean build, it will keep adding a new line.

Steps To Reproduce

1. I added openapi dependencies

    annotationProcessor("io.micronaut.openapi:micronaut-openapi:5.0.0-M4")
    compileOnly("io.micronaut.openapi:micronaut-openapi:5.0.0-M4")
    implementation("io.swagger.core.v3:swagger-annotations:2.2.15")

2. the server is added to the Application.groovy:

@Server(url = 'http://localhost:8080')
class Application {
    static void main(String[] args) {
        Micronaut.run(Application, args)
    }
}

3. create a openapi.properties file and change the target file:
   micronaut.openapi.target.file=./docs/openapi/api.yml
4. run gradle clean build 2 times or more. The first file will be ok, the second will duplicate the line and so on.

it also happens with @Securityscheme

security:
- bearerAuth: []
- bearerAuth: []

The default behavior works OK, because the generated api doc is inside the gradle build, which is deleted when you do gradle clean, so the file is generated from 0 each time you do gradle clean build and doesn't have duplicated lines. The problem only happens when you change the target file, so the file is not inside the gradle build folder and doesn't get deleted when running gradle clean.
