What is default timeout if request takes long to respond

I am integrating this client,

```ruby
client = Growthbook::FeatureRepository.new(endpoint: "", decryption_key: nil)
client.fetch
```

I can see fetch is using Net::HTTP.get_response

```ruby
uri = URI(endpoint)
res = Net::HTTP.get_response(uri)
```

What will be the default timeout in this case? OR
Is there a way, where we can define/pass open_timeout/read_timeout or timeout?

Start at Growthbook::FeatureRepository#fetch and its Net::HTTP.get_response call. Determine the current timeout behavior and whether configurable open_timeout, read_timeout, or timeout values are in scope. Done means the default and supported configuration are clarified and documented, or an agreed implementation target is defined.
