GitHub Actions config for running Jest tests with parallel jobs

@knapsack-pro/jest supports environment variables provided by GitHub Actions to run your tests. You have to define a few things in .github/workflows/main.yaml config file.

• You need to set KNAPSACK_PRO_TEST_SUITE_TOKEN_JEST environment variable in GitHub repository Settings -> Secrets. See creating and using secrets in GitHub Actions.
• You should create as many parallel jobs as you need with matrix.ci_node_total and matrix.ci_node_index properties. If your test suite is slow you should use more parallel jobs.

Below you can find config for GitHub Actions.
