Resolve TODO in content/markdown/guides/mini/guide-3rd-party-jars-remote.md

### Bug description

spotless has a bug with the comment so I'm removing this TODO from the code,
but it still needs to be checked

```
## Deploying Source Jars

To deploy a 3rd party source jar, packaging should be set to `java-source`,
and generatePom should be set to `fals-->

```

### Maven site URL where bug exists

https://maven.apache.org/guides/mini/guide-3rd-party-jars-remote.html

Start with content/markdown/guides/mini/guide-3rd-party-jars-remote.md and compare its “Deploying Source Jars” section with the Maven site page linked in the issue. Verify whether the packaging, classifier, and generatePom guidance is still correct, then update the documentation and remove or resolve the TODO comment.
