docs: A specific, existing section can be updated by making a PUT request on
  the URL for that project. Only the fields provided in the `data` block
  will be updated; any unspecified fields will remain unchanged. (note that
  at this time, the only field that can be updated is the `name` field.)
  
  When using this method, it is best to specify only those fields you wish
  to change, or else you may overwrite changes made by another user since
  you last retrieved the task.
  
  Returns the complete updated section record.
  
  @param  section The section to update.
  @return Request object
