Describe the bug

the picture in the online docs example does not reflect the text (swimlanes missing) nor the actual view of the example model in the repo.

To Reproduce

Steps to reproduce the behavior:

1. Go to 'https://docs.gaphor.org/en/latest/coffee_machine_logical.html#functional-boundary-behavior'
2. watch pictures below and read text, text says there is swimlanes, picture does not..
3. open model in example dir (coffee-machine.gaphor) and watch the swimlanes the text talk about..
4. doublechecked the svg that was uploaded and it does not contain any swimlanes.

Expected behavior

picture in the tutorial actually correctly represented, cause the example otherwise is a clever/fun way to make an example worthy of actually reading...

this is also the reason i took myself the time to atleast give a bug report that the picture does not match between the model and the generated example pictures, unless the pictures are not auto generated from the model it might be more that differ, but this one stuck out..

Screenshots

1. from online docs
   
2. uploaded copy for history reasons when the docs change..
   
3. exported as svg from my system from the model
   
4. exported as png on my system from the model
