fix: cron timing updated and action upgrade

[shubhamguptadream11]

Summary:

Problem: Duplicate issues were notified on discord channel in issue triaging section.

Changelog:

[GENERAL] [FIXED] - Changed cron timings to run at fix schedule and upgraded action for better debugging

Root cause:

• The cron job (cron: "0 /6 * *") is expected to run every 6 hours.
• Expected runs: 5:54 AM → 11:54 AM → 5:54 PM.
• However, the second run happened earlier at 11:37 AM instead of 11:54 AM.
• This caused duplicate pings for issues created around 5:42:24 AM.

Test Plan:

Tested action locally
