Disable auto-close for stale issues

[ShreyeshArangath]

Describe the bug

We currently mark issues as stale after 30 days and automatically close them 14 days later:

days-before-issue-stale: 30
days-before-issue-close: 14

This workflow assumes issues are tracked externally (for example, in JIRA), but we are not using JIRA or any other system to track active issues. As a result, user-reported issues that are still valid but have not received recent activity can be automatically marked stale and closed within ~45 days, even though they may not have been triaged or resolved. This risks losing legitimate issues and negatively impacts visibility into active issues.

To Reproduce
N/A

Expected behavior

We should look into disabling the stale issues similar to how Gluten does it today as it also does not use JIRA to track active issues.
