bump openapi-generator and sbt version

[polentino]

This PR aims to update openapi-generator to a more recent version, reason being: when compiling the generated code, this error appears

[error] [E1] openapi/src/main/scala/org/openapitools/client/core/JsonSupport.scala
[error]      object client is not a member of package sttp
[error]      did you mean client3?
[error]      L16: import sttp.client.json4s.SttpJson4sApi

this is due to the fact that the artifact was moved:

Note: This artifact was moved to:

com.softwaremill.sttp.client3 » core

I also bumped sbt version in order to be able to run it on macos, but that's not a hard requirement.
