Adding Dependencies

To add a dependency:

1. Modify the gradle/libs.versions.toml file and add the dependency to the correct section (or create a new section).\ Consult the Gradle documentation for more information on the libs.versions.toml file format.
2. Also mention the dependency in example/build.gradle.kts.
3. If the dependency is a Spoofax dependency (a library, application, or language that is part of Spoofax), also add the dependency to platform/build.gradle.kts.
