Yuya Nishihara b5f1728ffb templater: migrate op log to template language
The outermost "op-log" label isn't moved to the default template. I think
it belongs to the command's formatter rather than the template.

Old bikeshedding items:
- "current_head", "is_head", or "is_head_op"
  => renamed to "current_operation"
- "templates.op-log" vs "templates.op_log" (the whole template is labeled
  as "op-log")
  => renamed to "op_log"
- "template-aliases.'format_operation_duration(time_range)'"
  => renamed to 'format_time_range(time_range)'
