(Feature request) Export to PDF option

[brokoler]

Describe feature

Many PKMS tools offer the option to export notes to PDF format.
Right now Trilium does not support that feature.

Possible Workaround with issues:
A workaround is to "print" a note to PDF format via in-built operating system functions. Main issue is, that the whole formatting and dark mode background is being removed. So this workaround is not really an option, the output PDF looks bad.

An Export to PDF option would be great, with a selector option if light or dark theme (or probably just what is shown in Trilium client when doing the export) should be used. Notes can be shared really easy with a PDF export that doesn't break formatting.

@brokoler ,

Question: why should the PDF export support dark mode? I don't think I've seen a document with black background so far.
