Configure stale-management rules and cleanup syntax #46
Description
Description The current stale-management.yml workflow uses the default settings for the actions/stale action.
The Problem
Aggressive Closing: Without configuration, the action will tag and close all issues older than 60 days, including important bugs or pinned issues.
Generic Messages: The default stale message is generic and doesn't guide the user on what to do.
Redundancy: The repo-token input is no longer required for this action version.
Proposed Fix
Add configuration to exempt specific labels (e.g., pinned, security).
Customize the stale/close messages to be more friendly.
Remove the redundant repo-token line.
Fix the indentation of the schedule cron job for better readability.
