fix: allow colon before appDistZip in task-detection grep(DCD-5100)

[abhinav-genesis]

Multi-module gradle builds list subproject tasks as e.g. tam-deploy:appDistZip — the word-boundary regex added in 87065f4 didn't account for the colon, so appDistZip was never detected and the JFrog scan step was silently skipped for every client.

📋 Review Summary

This pull request correctly resolves an issue where the Gradle task detection logic fails to identify appDistZip when it is part of a multi-module project (such as tam-deploy:appDistZip). The proposed regex adjustment is a highly precise and targeted fix that preserves existing functionality while adding support for subproject task prefixes.

🔍 General Feedback

• Robustness: The regex update safely includes : within the prefix match, which is the standard separator for Gradle multi-module tasks.
• Accuracy: Testing confirms that this pattern matches expected subproject tasks (e.g. tam-deploy:appDistZip), root-level tasks, and indented tasks, while avoiding false matches on partially matching words.
• Safety: The change has no impact on existing single-module workflows and introduces no performance or security risks.
