Line Break Code (\n) Shown in Slack for GitHub Issue Descriptions with Newlines

[ntsk]

Describe the bug
When a newline is included in the description of a GitHub Issue, the line break code (\n) is displayed in Slack.
I am unsure whether this issue is caused by a change in GitHub or the Slack integration, but I recall that this behavior did not occur previously.

To Reproduce
Steps to reproduce the behavior:

1. Subscribe to issue creation notifications.
2. Create a new GitHub Issue with a newline in its description.
3. Check the output in Slack.

Expected behavior
Slack should display the description with proper line breaks instead of showing the line break code (\n).

For older issues, the description is displayed correctly without line break codes.
This behavior can be confirmed by adding a comment to an issue created in the past.
