Title: Fix warning message. It seems that the source :rubygems was deprecated.

When I executed `bundle update`, I found the following warning.

```
The source :rubygems is deprecated because HTTP requests are insecure.
Please change your source to 'https://rubygems.org' if possible, or 'http://rubygems.org' if not.
```
