Fix overlapping lines in header of submission PDF

[bmispelon]

I noticed that when the name of the lead on an application is quite long, the "meta" text in the PDF goes over several lines and ends up overlapping (see attached screenshots).

I tracked it down to what I believe is a missing line in apply/utils/pdfs.py (compared to the similar logic in handling split_title in the same function).

This seemed like a minor change so I didn't create an issue, please let me know if you'd prefer I did that.

Test Steps

1. Set up a hypha instance (with USE_PROJECTS=True for PDF download to work, see PDF download of submission fails when projects are not enabled #4566)
2. Log in as an admin user (so you have access to PDF download)
3. Change your display name to something fairly long (~80 characters, with spaces)
4. Go to a submission's detail page and download the PDF (Actions to take > More actions > Download PDF)

Looks good!
Nice catch on the meta text wrapping. It was happening when any of the meta fields like workflow, round name, lead name, etc., were long enough to wrap it in multiple lines.
