PropertiesMigrationListener wrongly reports property as deprecated when has group

From https://github.com/spring-projects/spring-boot/issues/35774#issuecomment-2322316896

Hi. I am running Spring Boot 3.3.3 and encountering this issue (with same configurations as in the original report). Could this issue be reopen?

Here is a Dockerfile to reproduce this warning log.

FROM eclipse-temurin:21

WORKDIR /tmp/demo

RUN apt-get update \
    && DEBIAN_FRONTEND=noninteractive apt-get install -y --no-install-recommends \
        curl \
        unzip

RUN curl \
        -G https://start.spring.io/starter.zip \
        -d type=gradle-project \
        -d javaVersion=21 \
        -d bootVersion=3.3.3 \
        -o /tmp/demo.zip

RUN unzip /tmp/demo.zip -d /tmp/demo

RUN ./gradlew dependencies

RUN sed -i '/dependencies {/a runtimeOnly("org.springframework.boot:spring-boot-properties-migrator")' build.gradle

RUN echo 'spring.kafka.ssl.trust-store-password=secret' >> ./src/main/resources/application.properties

CMD ["./gradlew", "bootRun"]

Output:
