Remove Helm Chart.lock File from Project Workflow

[jvoravong]

Description:
This PR removes the Chart.lock file from the project workflow due to the following reasons:

• Redundant with Locked Dependencies: All dependencies in related Chart.yaml are already locked to specific versions, making Chart.lock unnecessary.
• Local Developer Conflicts: Although the project does not use Chart.lock in source control, leftover Chart.lock files on local developer machines can cause errors or inconsistencies during dependency updates.

By removing Chart.lock from the workflow, we simplify dependency management and avoid potential issues in local development environments.
