Remove deprecated getFiles() instead of getResolvedArtifacts()

[wickdynex]

Description

This PR removes the usage of the deprecated getFiles() method in CheckBom.class and replaces it with the newer getResolvedArtifacts() method. The getFiles() method was deprecated due to its potential for incorrect behavior and its reliance on legacy API, while getResolvedArtifacts() provides a more reliable and modern approach to resolving dependencies.

Backward compatibility

This change is fully backward-compatible and does not affect the existing functionality of the BOM resolution process. The getResolvedArtifacts() method is a direct replacement for getFiles() and provides the same functionality but with updated API usage.

Additional Notes

To display warning correctly, I modified the build.gradle file, and use command ./gradlew :buildSrc:compileJava --rerun-tasks -Duser.language=en to show the warning obviously. But, I did't find the test class named CheckBomTests, but BomPluginIntegrationTests instead. I don't know whether it covers the method resolveBom() in CheckBom, so TDD workflow doesn't work. If there's some mistake, please leave a comment. Thanks~
