Title: Convert to_s when extracting a query parameter

This is a minor thing, but it supports the example usage in the documentation for testing with the query_parameter strategy. I opted to fix it in the strategy instead of calling to_s on the version match in case that had performance or other consequences for other strategies.

```ruby
BCApi::Application.config.view_versions.each do |supported_version|
...
end
```
