Rename two Rubocop cops in config that break the build (#2116)

Fix:
Error: The `Layout/FirstParameterIndentation` cop has been renamed to `Layout/IndentFirstArgument`.
(obsolete configuration found in .rubocop_rspec_base.yml, please update it)
The `Layout/IndentArray` cop has been renamed to `Layout/IndentFirstArrayElement`.
(obsolete configuration found in .rubocop_rspec_base.yml, please update it)
