[UX] - Project name and description should be actual values not placeholders #230

What would you improve?
In the subsection 'Project metadata' on the settings page, we can update the name and the description of the project. The current values are displayed as placeholders, but not as actual values. If we want to extend the name or the description of the project it needs to be written again from the beginning. This could be improved if the current values are set as actual values not as placeholders.
