Bump rubocop-rspec from 3.4.0 to 3.7.0

We're changing the `.rubocop.yml` file because we were getting a
warning:

```
rubocop-rspec extension supports plugin, specify `plugins:
rubocop-rspec` instead of `require: rubocop-rspec` in .rubocop.yml. For
more information, see
https://docs.rubocop.org/rubocop/plugin_migration_guide.html.
```
