Add support for Ruby 3.2.0 in Faraday v1.x (#1483)

* Run tests against Ruby 3.2

* Declare `DependencyLoader#new` with `ruby2_keywords` to fix Ruby 3.2.0

When adding a middleware that receives keyword arguments in the
constructor, the call from `DependencyLoader#new` fails because
the method is not defined using `ruby2_keywords`.

This adds the required `ruby2_keywords` declaration to
`DependencyLoader#new`, fixing the tests and getting Faraday v1.x
working with Ruby 3.2.0.

Fixes #1479.
