Populate PDF tag Author when exporting (also Subject, Keywords)

Your idea

Provide the ability to populate the PDF Author and other tags (Subject, Keywords).

Option 1. In MuseScore Project Properties, the first property is Arranger, which is typically the publisher of the score.
So Arranger could be mapped to the PDF Author automatically.

Option 2. A setting could be used for mapping to the standard or custom properties of the project.

Problem to be solved

When using the PDF in various apps and systems, such as Kindle etc, the PDF tags are extracted to summarize the document in the folders where they are presented. So having Authors populated is more helpful than Unknown or Undefined.
Also because such PDFs are often used or shared electronically, it is helpful to "stamp" them with the correct and easily identifiable tags.

• PDF Export does not set the PDF "Author" Property

Additional context

Workaround use external tools to set the "Author" and other tags.

exiftool -Author="My Name" "My Score.pdf"

exiftool -Author "My Score.pdf"
Author                          : My NAme

No files or tests are named. Start by locating the PDF export path and the MuseScore Project Properties handling, then determine whether Arranger or configurable standard/custom properties should supply PDF Author, Subject, and Keywords. Done means exported PDFs contain the chosen metadata and the behavior is covered by appropriate verification.
