* fix RuboCop error
RuboCop doesn't work by following error.
```
$ rubocop
Error: The `Style/TrailingCommaInLiteral` cop no longer exists. Please use `Style/TrailingCommaInArrayLiteral` and/or `Style/TrailingCommaInHashLiteral` instead.
(obsolete configuration found in .rubocop.yml, please update it)
```
it comes from RuboCop 0.53.0 [\[Fix #3394\] Separate Array & Hash Literal Comma configuration by garettarrowood · Pull Request #5307 · bbatsov/rubocop](https://github.com/bbatsov/rubocop/pull/5307)
* ci(CodeClimate): specify RuboCop version 0.54
* https://docs.codeclimate.com/docs/rubocop#section-using-rubocop-s-newer-versions
* [RuboCop 0.55.0 is not available yet](https://github.com/codeclimate/codeclimate-rubocop/issues/121) on CodeClimate rubocop channel
* Exclude javascript locale files form Code Climate's duplication
engine. It is silly to have duplication check with locale files.
They are supposed to look similar.
* Prevent unnecessary blocking for translation updates (like #1661)
