upgrade faraday to >= 2.0.1

this removes faraday_middleware (due to faraday 2.0 changes), adds faraday-multipart and updates related class references.

additionally, faraday's minimum version is now set at 2.0.1 per https://github.com/lostisland/faraday/blob/main/UPGRADING.md to avoid missing net_http issues
