Basic Info

The Faraday README.md states: "Currently that means we support Ruby 2.6+"

Rubygems.org states that the required ruby version is >= 2.4

This seems contradictory.

• Faraday Version: 1.7.0
• Ruby Version: 2.5.3

Issue description

I need to use the most recent version of Faraday that supports 2.5.3. There's likely no code change for this--just documentation to explain why, and then how to find the the actual version that supported a specific ruby version.

Steps to reproduce

Read the README, visit Rubygems.org and check the required ruby version information on the right side of the view when you select a specific Faraday version.
