* remove trailing whitespace * %i delimiters use square brackets When I ran rubocop in my project, the following warnings popped up ``` db/migrate/20220227060245_create_versions.rb:31:8: C: [Correctable] Layout/TrailingWhitespace: Trailing whitespace detected. # ^ db/migrate/20220227060245_create_versions.rb:33:41: C: [Correctable] Layout/TrailingWhitespace: Trailing whitespace detected. # t.datetime :created_at, limit: 6 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ db/migrate/20220227060245_create_versions.rb:36:26: C: [Correctable] Style/PercentLiteralDelimiters: %i-literals should be delimited by [ and ]. add_index :versions, %i(item_type item_id) ^^^^^^^^^^^^^^^^^^^^^ ```
