Typst template: use content rather than string...

...for title, author, date, email.

Fixes #9823 (escaped `\@` in rendered email).
Allows formatting in title, author, date, and email fields.
Since the PDF metadata requires a string, and typst only
converts the title to a string (not the authors), we use
a small function content-to-string to do this conversion.
