Enforce platform constraints for resolving conditional dependencies in QuarkusComponentVariants

[reaver585]

Summary
This was mentioned in #49714 (comment). Conditional dependencies resolved in Gradle with QuarkusComponentVariants are not guaranteed to respect platform/BOM version constraints, leading to potential drift outside the supported platform versions.

Expected Behavior
Conditional dependency versions should always resolve within the platform’s defined constraints (as declared in the BOM).

This is actually not specific to QuarkusComponentVariants. To be accurate, it the target artifact of the conditional dependency that needs to be aligned with the version constraints enforced in a project.
