Title:

Faraday request returns 403 while equivalent curl request returns 200

Description:

### Issue
When making a request using Faraday with the following Ruby code:

```ruby
response = Faraday.get('https://circle.so') do |req|
  req.headers['accept-encoding'] = "gzip"
  req.headers['accept-language'] = 'en-US,en;q=0.9,es-US;q=0.8,es;q=0.7,la;q=0.6'
  req.headers['cache-control'] = 'max-age=0'
  req.headers['priority'] = 'u=0, i'
  req.headers['sec-ch-ua'] = '"Google Chrome";v="131", "Chromium";v="131", "Not_A Brand";v="24"'
  req.headers['sec-ch-ua-mobile'] = '?0'
  req.headers['sec-ch-ua-platform'] = '"macOS"'
  req.headers['sec-fetch-dest'] = 'document'
  req.headers['sec-fetch-mode'] = 'navigate'
  req.headers['sec-fetch-site'] = 'same-origin'
  req.headers['sec-fetch-user'] = '?1'
  req.headers['upgrade-insecure-requests'] = '1'
  req.headers['user-agent'] = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36"
end

The response consistently returns 403 Forbidden, while using an equivalent curl command, it returns 200 OK.

Equivalent curl command:

curl -X GET "https://circle.so/" \\
  -H "accept-language: en-US,en;q=0.9,es-US;q=0.8,es;q=0.7,la;q=0.6" \\
  -H "cache-control: max-age=0" \\
  -H "priority: u=0, i" \\
  -H "sec-ch-ua: \"Google Chrome\";v=\"131\", \"Chromium\";v=\"131\", \"Not_A Brand\";v=\"24\"" \\
  -H "sec-ch-ua-mobile: ?0" \\
  -H "sec-ch-ua-platform: \"macOS\"" \\
  -H "sec-fetch-dest: document" \\
  -H "sec-fetch-mode: navigate" \\
  -H "sec-fetch-site: same-origin" \\
  -H "sec-fetch-user: ?1" \\
  -H "upgrade-insecure-requests: 1" \\
  -H "user-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36"

Expected behavior

Both the curl command and the Faraday request should return 200 OK.

Actual behavior

• Faraday response: 403 Forbidden
• Curl response: 200 OK
