• Issue: Clarify <PRODUCT_HOME> definition in configuration instructions- challenge-questions product-is#26046

• Type: Documentation - Bug Fix

• Summary: Added clear definition of <IS_HOME> placeholder in challenge questions configuration documentation to minimize setup errors and improve clarity for new users. The definition explains that <IS_HOME> refers to the root directory where WSO2 Identity Server is installed or extracted, with version-specific examples (e.g., /home/user/wso2is-6.0.0).

• Affected Versions:

  • 5.11.0 - managing-challenge-questions.md
  • 6.0.0 - challenge-question.md
  • 6.1.0 - challenge-question.md

• Style Scope Verification: Microsoft Style Guidelines have been applied only to newly added content without modifying existing content style.

• Verification: mkdocs build passed successfully for version 6.0.0 (representative build test)

The changes ensure that users unfamiliar with WSO2 terminology can easily understand where to locate configuration files, reducing confusion and setup errors.
