Fix BOM version resolution for sibling modules in dependencyManagement

[Hiteshsai007]

Description

This PR addresses, fixing a regression in Maven 4 where version and groupId inference were skipped for dependencies declared within the <dependencyManagement> section of a BOM-packaged project.

Issue: #11147

How it works:
I updated the transformFileToRaw method within DefaultModelBuilder to ensure that model.getDependencyManagement().getDependencies() is processed with the same inferDependencyVersion and inferDependencyGroupId logic that is already applied to direct dependencies (model.getDependencies()).

Why this is necessary:
Previously, if a BOM subproject declared sibling reactor modules within its <dependencyManagement> block but omitted the <version> tags (expecting them to be resolved from the reactor), the transformation to the raw model would skip them entirely. This resulted in the installed consumer POM missing the required version tags for those managed dependencies. This change ensures that the reactor versions are properly inherited and written to the consumer POM.

Testing:

• Successfully verified the fix locally using the bom-example reproducer provided in the issue, confirming that the resulting consumer POM now contains the correctly inferred versions.
• Formatted with spotless:apply and successfully passed all maven-impl unit tests. Note: Due to the complexity of simulating a full multi-module reactor state directly within DefaultModelBuilderTest, a standalone unit test for this specific code path was omitted in favor of the reproducer validation.

  This may not always be possible but is a best-practice.
• Run mvn verify to make sure basic checks pass.

1. Needs tests
2. Needs a link to github issue

@elharo Thanks for the review! I've addressed both items:

1. Tests: Added testBomDependencyManagementVersionInference() in DefaultModelBuilderTest that verifies version inference works for dependencies in <dependencyManagement>, not just <dependencies>. The test registers a sibling module in the reactor, then calls transformFileToRaw on a BOM model with a managed dependency missing its version, and asserts the version is correctly inferred.

2. Issue link: Updated the PR description to include Fixes #11147.

All 13 tests in DefaultModelBuilderTest pass with zero failures.
