Subject: [PATCH] SWPROT-8953: Add recipe to pull UnifySDK dependency

This file is shared a single commit,
to allow pick between projects (eg: z-wave-protocol-controller)
consuming UnifySDK since the monorepo has been shrinked.
Feedback welcome.

Note values can be ajusted from env,
it can be usefull for github actions with fork,
if using private one make sure to pass the token in the build env:

    UNIFYSDK_GIT_REPOSITORY="https://<TOKEN>@github.com/rzr/UnifySDK"
