/ask what are the changes in this pull-request about?

[ubiquity-os-beta]

This pull request primarily focuses on simplifying and consolidating user roles within the command-start-stop plugin. Previously, multiple roles such as admin, member, collaborator, contributor, owner, billing_manager, write, and read were used to manage permissions and task assignments. The changes introduce a streamlined role system by grouping these into two main categories: collaborator and contributor.

Key modifications include:

• Configuration Updates: The .ubiquity-os.config.yml and plugin-input.ts files have been updated to reflect the new role structure, removing the complexity of multiple roles and setting default limits for collaborators and contributors.

  maxConcurrentTasks:
    collaborator: 10
    contributor: 2

• Code Refactoring: Functions responsible for determining user roles and task limits, such as getUserRoleAndTaskLimit, have been refactored to accommodate the new roles. Helper functions like isAdminRole and isCollaboratorRole ensure accurate role assignments.

• Testing Enhancements: Test cases in files like roles.test.ts and configuration.test.ts have been updated to validate the new role configurations and ensure that task limits are enforced correctly based on the simplified roles.

• Permissions Handling: The logic for starting and stopping tasks has been adjusted to verify user permissions against the new collaborator and contributor roles, ensuring that only authorized users can perform these actions without unnecessary restrictions.

• Documentation: The README has been revised to reflect the changes in role management, providing clearer guidance on how hunters can use the /start and /stop commands under the new role system.

Overall, these changes aim to enhance maintainability, reduce configuration complexity, and ensure a more straightforward permission management system within the plugin.

Updated configuration for this as well. I wish we had the frontend for this because I am sure I missed some repos with custom configs.
