fix(deps): use rack-reverse-proxy pact-foundation fork

[YOU54F]

• fixes issue NoMethodError: undefined method `strip' for nil:NilClass #43

• updates to rack 3

  • enabled via https://github.com/pact-foundation/rack-reverse-proxy/tree/feat/rack_2_and_3_compat

• update to rack-test 2.1.0

## Reproduce

Create a simple ruby server, which returns a set-cookie header (Rack 3 so need to be lowercased)

require 'json'

class HttpRequestHandler
  def call(_env)
    response_body = JSON.generate(['foo'])
    [200, {
      'content-type' => 'application/json; charset=utf-8',
      'set-cookie' => '__cf_bm=_somebase64encodedstringwithequalsatthened=; array=awesome'
    }, [response_body]]
  end
end

run HttpRequestHandler.new

Save and run with rackup -p 9393

Save this following pact to pact.json

{
    "consumer": {
      "name": "a"
    },
    "provider": {
      "name": "b"
    },
    "interactions": [
      {
        "description": "A request",
        "request": {
          "method": "GET",
          "path": "/",
          "headers": {
            "accept": "application/json"
          }
        },
        "response": {
          "status": 200,
          "headers": {
            "Content-Type": "application/json; charset=utf-8"
          },
          "body": ["foo"],
          "matchingRules": {
            "$.body": {
              "match": "type"
            }
          }
        }
      }
    ],
    "metadata": {
      "pactSpecification": {
        "version": "2.0.0"
      }
    }
  }

Run the verifier from the repo locally - passes

bundle exec bin/pact verify pact.json --provider-base-url http://localhost:9393 --verbose --log-level debug

Build the image

docker build -t pact-cli .

run it

docker run --rm -v $PWD:/test -it pact-cli verify /test/pact.json --provider-base-url http://host.docker.internal:9393 --verbose --log-level debug

passes - output

INFO: Reading pact at /test/pact.json


Verifying a pact between a and b
  A request
    with GET /
      returns a response which
        has status code 200
        has a matching body
        includes headers
          "Content-Type" which equals "application/json; charset=utf-8"

1 interaction, 0 failure

versus this which fails

docker run --rm -v $PWD:/test -it pactfoundation/pact-cli:1.3.0.11 verify /test/pact.json --provider-base-url http://host.docker.internal:9393 --verbose --log-level debug

error

     Failure/Error: replay_interaction interaction, options[:request_customizer]
     
     NoMethodError:
       undefined method `strip' for nil
     # ./bin/pact:15:in `<top (required)>'

For completeness, I've also tested this out with the latest pact_verifier_cli (the rust based version, and it works)

pact_verifier_cli --file pact.json --hostname localhost:9393

Verifying a pact between a and b

  A request (3ms loading, 190ms verification)
    returns a response which
      has status code 200 (OK)
      includes headers
        "Content-Type" with value "application/json; charset=utf-8" (OK)
      has a matching body (OK)
