Add an option for "export to pdf" to create a pdf without a title in the metadata

Use case or problem

When a pdf is exported in recent versions the pdf title is set as

note_name - vault_name - obsidian_version

This appears when you open the pdf in a browser and makes it more annoying to parse different pdfs. This also makes it look more professional

Proposed solution

Add a toggle to remove the title in the export to pdf settings.

Current workaround

Use an external program or website to remove the title.
