Webrick as a gem dependency

[toncid]

Issue summary

As of v9.5 Webrick is a shopify_api gem dependency, which is very strange to see.

Expected behavior

It is strange to see it as a dependency, Webrick should be optional.

Actual behavior

The v9.5 of the gem now lists webrick as a dependency:

    shopify_api (9.5)
      activeresource (>= 4.1.0, < 6.0.0)
      graphql-client
      rack
      webrick  <<<<<<<<<<<<<<<<

Steps to reproduce the problem

1. Upgrade the shopify_api gem to v9.5.
