Add linebreak to task gantt

[tiarasilva]

Description

In the current version of Mermaid's Gantt charts, it appears that line breaks (e.g., using
tags or newline characters such as \n) within task descriptions do not produce the intended effect of creating a new line. While these HTML tags and escape sequences work as expected in section titles, they seem to be ineffectual within the task descriptions.

Steps to reproduce

1. Create a Gantt chart
2. Insert a line break on task description
3. Render the Gantt
