refactor how we make an http request with proxy

- 1. Net::HTTP::Proxy is obsolete
	- Refactor the current method to pass proxy arguments straight to Net::HTTP.new
	- [https://apidock.com/ruby/Net/HTTP/Proxy/class](https://apidock.com/ruby/Net/HTTP/Proxy/class) <- obsolete
	- [https://apidock.com/ruby/Net/HTTP/new/class](https://apidock.com/ruby/Net/HTTP/new/class) <- new way
	- This wil also make it easier to stub
- 2. Tiktok parser seems to be making the http request from within the parser
	- We make an http request from tiktok_item.rb, get_tiktok_api_data: https://github.com/meedan/pender/blob/1cb4a2b8b9afbe49ef82407588716026d05da8b4/app/models/parser/tiktok_item.rb#L55C1-L63C8
	- Here we are NOT using the proxy, we should be using it for tiktok
- All http requests should be coming from the same place
