Dependency Scanning: Add support for Java 25 LTS and Gradle 9.1
<!--This template is a great use for issues that are feature::additions or technical tasks for larger issues.-->
### Proposal
Extend Dependency Scanning support to include:
- Java 25
- Gradle 9.1
Java 25 was released in September 2025 as the latest Long-Term Support (LTS) release.
Currently, GitLab Dependency Scanning [only supports](https://docs.gitlab.com/user/application_security/dependency_scanning/#supported-languages-and-package-managers) Java 8, 11, 17, and 21 LTS versions. According to the [Gradle compatibility matrix](https://docs.gradle.org/current/userguide/compatibility.html), Java 25 requires Gradle 9.1.0 or later. Gradle 9.x is not supported and fails with the following [error](https://docs.gitlab.com/user/application_security/dependency_scanning/troubleshooting_dependency_scanning/#dependency-scanning-nebula-lock-creation-fails-due-to-unsupported-gradle-version) due to breaking API changes.
### Why this issue is no longer relevant?
Because with the new DS analyzer (19.0) we can support users with Java 25. See https://gitlab.com/gitlab-org/gitlab/-/work_items/590066#note_3369569644
