URL not included in response hash

[aaronstillwell]

Basic Info

• Faraday Version: 2.6.0 (though issue is present in latest afaik)
• Ruby Version: 3.1.2

Issue description

The URL isn't available on the response object after being converted to a hash. When using certain middleware (e.g https://github.com/tisba/faraday-follow-redirects) the URL on the response isn't necessarily the same as on the request. This information can be therefore valuable to have to check the final URL used to fetch the response.

Steps to reproduce

res = Faraday.get 'https://httpbin.org/status/200'
puts res.env.url
# => #<URI::HTTPS https://httpbin.org/status/200>

dumped = Marshal::dump(res)
loaded = Marshal::load(dumped)

puts loaded.env.url
# => nil

Remediation

Assuming there are no unintended consequences of adding the url to the to_hash object, this should be an easy modification to make. (I am happy to follow up with a PR after discussion here).

faraday/lib/faraday/response.rb

Lines 61 to 66 in 0e16de8

	def to_hash
	{
	status: env.status, body: env.body,
	response_headers: env.response_headers
	}
	end

This looks like a safe change and it makes sense in the context mentioned in the issue.

I'd be happy to review a PR with sufficient test coverage 👍
