Change default PDF version to 1.6 (released in 2004)

We already write markup which is newer than 1.5, but the PDF version was
not changed. Fix the one violation I'm aware of.

Printing is left unchanged, similar to how commit
99ac4ee05b039166eedfe361fb985682fd92dd13 (Change default PDF version to
1.5, 2018-04-24) updated the default last time.

(cherry picked from commit 141e0449fdab89384564659191492b698e4b13d8)
