No license in pom file

[ganadist]

I'm using Google OSS License plugin to show libraries' licenses to end users.

And after add commonmark-java dependency, I found license activity don't show license of commommark-java

I found there is license declaration on root (commonmark-parent) project. https://github.com/commonmark/commonmark-java/blob/main/pom.xml#L264-L270

But, main java project(commonmark-parent) don't have license declaration. https://github.com/commonmark/commonmark-java/blob/main/commonmark/pom.xml

And there is no license declaration on Maven POM File. https://central.sonatype.com/artifact/org.commonmark/commonmark

Could you add license declaration on POM file of commonmark-java?
