Published Gradle module file is missing `javadocElements` and `sourcesElements`

[philwebb]

https://repo1.maven.org/maven2/org/springframework/spring-core/7.0.9/spring-core-7.0.9.module is missing javadocElements and sourcesElements making javadoc and source jars harder to download.

The elements should be added similar to https://repo1.maven.org/maven2/org/springframework/boot/spring-boot/4.1.1/spring-boot-4.1.1.module
