[Bug] Broken discussions URL in ISSUE_TEMPLATE config

[d-oit]

Description

In .github/ISSUE_TEMPLATE/config.yml (line 5), the discussions URL is:

url: https://github.com/discussions

This is an invalid URL. It should be:

url: https://github.com/d-oit/do-knowledge-studio/discussions

Impact

• Users clicking "Ask a Question" in the issue template get redirected to a non-existent page
• Poor contributor experience

Fix

Update the URL to the correct discussions page for the repository.

Acceptance Criteria

• URL updated to https://github.com/d-oit/do-knowledge-studio/discussions
