Accessibility issue: PDF Lacks Descriptive Title

[alexarobu]

Describe the bug
Hi,

It appears that when you download a PDF version of a record (from the individual record view) there is no title included. I couldn't find where this is set, would you be able to help point me in the right direction?

To Reproduce
Steps to reproduce the behavior:

1. Go to any metadata record page
2. Download the record as PDF
3. Open the PDF in Acrobat Reader Pro or PAC (https://pdfua.foundation/en/pdf-accessibility-checker-pac/)
4. See error Title - Failed in the Accessibility Checker tab for Acrobat Reader Pro or Title (missing) in PAC (see screenshot below)

Expected behavior
It is expected that a descriptive title (like the metadata record title, for example) is present when the PDF is opened.
