Enable tests on fork by updating repository reference

[jakauppila]

Update chef/chef references to utilize the environment variable GITHUB_REPOSITORY so that builds complete successfully via forks on Github.

Signed-off-by: Jared Kauppila Jared.Kauppila@sentry.com

Description

Currently when you fork chef/chef and attempted to execute the Github actions, it attempts to pull down the source code from the git commit at chef/chef which obviously does not exist.

This change will reference the owner/repository defined via GITHUB_REPOSITORY in Github actions so that the tests can run successfully. If that environment variable does not exist, it will default to chef/chef
