add Harmony as a VPM dependency

When a user adds this package they no longer have to manually add Harmony.

I have a simple example with this here: https://konsti219.github.io/TestPackage-vpm/

Thanks for noting this; not having it as a dependency is an intentional choice. I thought long and hard about this when finalizing the release structure, and considered both options. There's a couple of problems with adding it as a dependency:

• Other tools bundle Harmony (ControllerEditor, UdonSharp), which can cause conflicts if RATS considers a specific Harmony install the one it depends on
• I can't limit to one Harmony install, or create a dependency that can be satisfied by multiple packages (some VPM, some not)

Ultimately, this led me to not include Harmony by default. This isn't ideal, but it's the best compromise for compatibility, in my opinion.

My ideal case would be for VRChat to include Harmony in the com.vrchat.base SDK package, so that RATS can be satisfied by a dependency to that (with a manual release without the dep for non-VRC use cases).

Thanks for explanation

RATS 1.1.4 now depends on com.vrchat.base ^3.4.0, which bundles Harmony, and marks one.razgriz.harmony-vpm as a legacy package, which will cause VCC to remove it (in VCC 2.1.4 and up).

This automates handling of the Harmony dependency for VCC projects.
