An edit (pencil) icon is visible next to links to diagrams in PDF exports

[raphj]

Describe the bug

This is how diagrams are displayed:

• the diagram itself
• the diagram name, clickable, with a pencil icon

This is fine except for PDF exports, because we don't know if the person looking at the PDF has edit rights on the diagram.

Steps to reproduce
Steps to reproduce the problematic behavior:

1. Create a diagram
2. export the document as PDF

Expected behavior

No edit icon next to the clickable diagram name in the PDF

Actual behavior

There is an edit icon next to the clickable diagram name in the PDF
