Update to doctemplates-0.10.0.1

0.10.0.1
* Don't rely on aeson Object being implemented as a HashMap. This change is
  needed for doctemplates to compile against aeson 2.0.0.0.

0.10
* Change rendering and conditional behavior with booleans. Previously,
  $if(foo)$ evaluated to false iff foo would render as the empty
  string. This forced us to render a boolean False value as an empty
  string, rather than false. And this has caused various problems with
  templates (#16, jgm/pandoc#7402). Now, boolean False values render as
  false -- just as True values render as true. And conditionals are now
  sensitive to booleans, so $if(foo)$ evaluates to false when foo is a
  boolean False value, even though it would render as the nonempty string
  false.
