Native Support for Adventure Library

[zvyap]

This pull request addresses issue #29, which I opened previously, to add native support for the Adventure API Component.

Changes in this PR

• Added a new module: configlib-adventure, shaded into the Paper and Velocity modules (since both natively support Adventure).
• Implemented serializers for Component, Key, and Sound.
• Added related tests (some were initially AI-generated, but I reviewed, modified, and approved them).
• Added related Javadocs.
• Updated readme

Notes

• I noticed that running gradle test at the root or within any module only executed tests in the core module. I am not sure whether this behavior was intentional.
  I modified the behavior so that:

  • Running tests at the root executes all tests across all modules.
  • Running tests inside a specific library module runs only that module’s tests.
  • Running tests inside a plugin module continues to run core tests, as per the previous behavior.

  If the previous test configuration was intentional, please let me know and I will revert the changes accordingly.

• I also fixed two failing tests in the core module that were caused by Windows-specific behavior (as shown in the screenshot). All core module tests now pass on Windows.

• If you are not satisfied with the changes mentioned above, I am willing to revert or adjust them as needed.
