Published POMs are missing license info

[li-wjohnson]

For example:
https://dl.bintray.com/kotlin/kotlinx/org/jetbrains/kotlinx/kotlinx-collections-immutable-jvm/0.3.3/kotlinx-collections-immutable-jvm-0.3.3.pom

Compare with:
https://bintray.com/kotlin/kotlinx/download_file?file_path=org%2Fjetbrains%2Fkotlinx%2Fkotlinx-coroutines-core%2F1.4.2%2Fkotlinx-coroutines-core-1.4.2.pom

This is causing issues with our license compliance checks.

In the latest release, 0.3.4, the license information is included.
Please update to the latest version and check if the problem remains.
Thank you for your feedback!
