Cannot build PDFs when using latest version of beautifulsoup4 >= 4.10

Hi,

Environment: Python 3.9, Alpine 3.14 MkDocs version: 1.1.2 Plugin version: 0.9.3

When building with mkdocs build:

AttributeError: can't set attribute

It seems related by changes on tag introduced in beautifulsoup4 v4.10+. Not yet sure, anyway, a workaround is to pip install first beautifulsoup4==4.9.3 then install this plugin to make it works again.
