In case of large DrawIO diagrams, today it is sometimes impossible to display it totally on the screen. This quick workaround provides a way to enable a scrollbar if the width of the diagram is higher than the browser/screen width.

What does this PR do?
It adds the ability to automatically enable scrollbars when a DrawIO diagram width is higher than the browser/screen width.
Why this PR?
We have documentation with complex diagrams, that are sometimes very big.
Unfortunately, the access to these diagram is today unusable, beacause a part of them is not displayed. The reason is that their size is not adapted to the browser/screen size OR a scrollbar is not enabled.
I have decided to suggest this small fix (a new field in the CSS class .diagram) as it is a simple workaround enabling scrollbars.
