docs: pdfdocs: One-half spacing for CJK translations
CJK documents are much easier to read with a wider baseline stretch. Applying onehalfspacing option of "setspace" package looks reasonable. Note: \usepackage{setspace} needs to be before that of hyperref in the preamble. The 'extrapackages' key (available since Sphinx 2.3) is for this purpose. For systems with Sphinx < 2.3, dummy commands of \onehalfspacing and \singlespacing are provided instead. One-half spacing is not effective in LaTeX sources generated by such revisions of Sphinx.
