/Users/koic/src/github.com/rails/rails/railties/lib/rails/generators/migration.rb:66:
warning: Passing safe_level with the 2nd argument of ERB.new is
deprecated. Do not use it, and specify other arguments as keyword
arguments.
/Users/koic/src/github.com/rails/rails/railties/lib/rails/generators/migration.rb:66:
warning: Passing trim_mode with the 3rd argument of ERB.new is
deprecated. Use keyword argument like ERB.new(str, trim_mode: ...)
instead.
/Users/koic/src/github.com/rails/rails/railties/lib/rails/generators/migration.rb:66:
warning: Passing eoutvar with the 4th argument of ERB.new is
deprecated. Use keyword argument like ERB.new(str, eoutvar: ...)
instead.

```
This PR suppresses the above deprecation warnings in Ruby 2.6.0-dev.
This warning is due to the interface of `ERB.new` will change from Ruby 2.6.
> Add :trim_mode and :eoutvar keyword arguments to ERB.new.
> Now non-keyword arguments other than first one are softly deprecated
> and will be removed when Ruby 2.5 becomes EOL. [Feature #14256]
