[Bug]: maven source artifact does not contain sources from shaded artifacts

Module

Core

Testcontainers version

1.17.3

Using the latest Testcontainers version?

Yes

Host OS

not related

Host Arch

not related

Docker version

not related

What happened?

The testcontainer maven source artifacts (e.g. https://repo1.maven.org/maven2/org/testcontainers/testcontainers/1.17.3/testcontainers-1.17.3-sources.jar) does not contain sources for shaded artifacts.

So any classes which are put into: org.testcontainers.shaded are missing.

Relevant log output

_No response_

まず、Core モジュールの Maven パッケージング設定と、リンクされた 1.17.3 URL にあるソースアーティファクトを調べます。ソース JAR に含まれるソースと org.testcontainers.shaded 配下に配置されたクラスを比較し、その後、再ビルドしたソースアーティファクトに期待される shaded ソースが含まれていることを確認します。
