[aantia]

Describe the bug
Journal links don't work to fillable pdfs, although they work fine for static ones.

To Reproduce
Steps to reproduce the behavior:

1. Create a new fillable pdf.
2. Create a link to that pdf in a journal, e.g. @pdf[New PDF|page=1]{New PDF}
3. Click on it.
4. This error is thrown: Error: Provided entity was not a journal entry.

Expected behavior
The pdf should open.

Version Information:

• Tested in Brave and Chrome
• FoundryVTT Version 9 - Build 245
• PDFoundry 0.9.1
• Tested in my own system with tons of modules and in the V5 system in a new world with no other modules than PDFoundry

At the moment this isn't supported, but I'd like it to be in the future.
