Fix Rubocop errors

Rubocop complained about the following things:

  lib/page/term_table.rb:90:11: C: Align the elements of a hash literal if they span more than one line.
            person:          person,
            ^^^^^^^^^^^^^^^^^^^^^^^
  lib/page/term_table.rb:91:11: C: Align the elements of a hash literal if they span more than one line.
            term:            term,
            ^^^^^^^^^^^^^^^^^^^^^
  lib/page/term_table.rb:91:32: C: Avoid comma after the last parameter of a method call.
            term:            term,
                                 ^

This commit fixes those errors in a way that seems to fit the local
style in this file.
