Granularize LeanPipe with Funnel package distribution and reorganize Publisher structure

[Dragemil]

The main package LeanCode.Pipe, which included Funnel relevant stuff is being split into:

• LeanCode.Pipe (but without Funnel stuff)
• LeanCode.Pipe.Funnel.Instance - for stuff to deploy a Funnel Proxy instance
• LeanCode.Pipe.Funnel.Publishing - for stuff to set up LeanPipe in a system that publishes with LeanPipe through Funnel
• LeanCode.Pipe.Funnel.Core - a transitive package for the two above, shouldn't be used directly tbh

There shouldn't be any breaking change for anyone using LeanPipe.Pipe without the Funnel, but there are namespace changes in the Funnel Publishing package. Since basically no one relevant uses Funnel, I don't consider this a breaking change.

This PR doesn't change any functionality, even though the diff isn't that small.

Pull request overview

This PR restructures the LeanCode.Pipe package by extracting Funnel-related functionality into separate packages: LeanCode.Pipe.Funnel.Core, LeanCode.Pipe.Funnel.Instance, and LeanCode.Pipe.Funnel.Publishing. The main package now contains only the core LeanPipe functionality without Funnel dependencies.

Key Changes:

• Split Funnel functionality into three dedicated packages
• Updated namespace from LeanCode.Pipe.Funnel.FunnelledService to LeanCode.Pipe.Funnel.Publishing
• Reorganized test structure with dedicated Funnel.Tests directory
• Updated CI/CD workflows to build and publish new packages

It would be good to update the docs on using the funnel. Other than that

Yeah, got it quite near in my backlog
