Count all open incidents per priority

[bhavyaa30]

PR Description: We want to dynamically calculate the number of open incidents for each priority level (1 - Critical, 2 - High, 3 - Moderate, 4 - Low) using server-side scripting. This script uses GlideAggregate to count the number of open incidents per priority dynamically. Useful for dashboards, automated scripts, or business rules.

Script looks good (I like the IIFE pattern!!), however your readme file is too vague. Please extend it by using correct markdown syntax so we get real headlines and paragraphs (refer to https://www.markdownguide.org/basic-syntax/).
Then I will approve the PR.
Looking forward to your changes!
