Update upstream tracking strategy via own master branch (#36)

* Update upstream tracking strategy via own master branch

Changed to create merge PR from it's own master branch which is
automatically synced with apple:master.
Creating merge PR from apple:master sends CI failure email to apple
members, so we need to change tracking strategy.

New Tracking steps:

1. sync master branch from apple:master
apple:master -> swiftwasm:master

2. create merge PR from swiftwasm:master
swiftwasm:master -> swiftwasm:swiftwasm

* Use released artifact instead of Actions artifacts directly
