Bold text not working in Greewing theme

[fagnertakeshi]

I am using the Greewing theme in Kanboard, and I've noticed that the bold text formatting is not working as expected. When I try to make text bold, it doesn't display in bold.

Steps to Reproduce:

Install and activate the Greewing theme in Kanboard.
Create a new task or edit an existing one.
Attempt to make text bold using ** or __ around the text.
Expected Result:
The text should be displayed in bold.
