compability with pdfmanagement

[u-fischer]

As you are using tagpdf which requires the pdfmanagement code, you shouldn't use the primitive \pdfcatalog. That is not compatible.

@u-fischer What we should use instead it?

[u-fischer]

probably nothing, if I saw right you are using it to set the language, and that can be set with
\DeclareDocumentMetadata{lang=de-De}. Also the pdfmanagement will set Lang initially to en-US anyway.
