Improve contents of generated pom files

Previously, the generated pom files were uncustomised and relied on
Gradle’s default output. Such pom files are problematic for a couple
of reasons: they include test dependencies and they don’t include the
metadata that’s required for publishing to Maven Central.

This commit customises the generated pom files to include the required
metadata and to remove any test dependencies.
