`pulumi package gen-sdk --language java` produces an invalid `gradle.build` with a multi-line package description

What happened?

When working on pulumi-terraform, I saw that Java failed to build with this error message:

make -C ../../.. install_java_sdk test_integration TAGS=java
gmake: getcwd: No such file or directory
gmake: Entering directory '/Users/ianwahbe/go/src/github.com/pulumi/pulumi-terraform'
cd sdk/java && gradle --console=plain build

Welcome to Gradle 8.13!

Here are the highlights of this release:
 - Daemon JVM auto-provisioning
 - Enhancements for Scala plugin and JUnit testing
 - Improvements for build authors and plugin developers

For more details see https://docs.gradle.org/8.13/release-notes.html

Starting a Gradle Daemon (subsequent builds will be faster)

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.13/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

Output of pulumi about

The pulumi about output isn't really relevant, but here is the version:

pulumi version
v3.159.0

Additional context

Multi-line descriptions have not been an issue in other languages, so I would expect this to work here.

Vote on this issue by adding a 👍 reaction.
To contribute a fix for this issue, leave a comment (and link to your pull request, if you've opened one already).

Start by running pulumi package gen-sdk --language java with the multi-line package description and inspect the generated sdk/java/build.gradle, especially the publishing block and its description. Run gradle --console=plain build; done means the generated Gradle file accepts the description and the Java build completes successfully.
