feat: update_project_releases uses SW360 PATCH API call now

This removes our own patch handling for adding releases and also allows
to pass a dict with release datails now, e.g. to set relation or project
mainline state for a linked release.

 # SW360 Base Library for Python
 
+## UNRELEASED
+
+* use SW360 support for `update_project_releases(..., add=True)` instead of our own code.
+  This allows to pass a dict with release details (e.g. project mainline state or relation).
+
 ## V1.8.1
 
 * `delete_project` now works properly. Before it could have happened the you get a `JSONDecodeError`.
