chore: Update faraday dependency version range

[shrutiburman]

Fixes

This will help in application/json body types, we wont have to do any unpacking of json body manually because faraday 2.0+ handles it.
Also, faraday 2.0+ requires ruby version to be 2.6 or higher, so to be future compatible we'd be dropping 2.5 which was EOL in 2021
