Workflow level `env` does not work properly in all fields.

Problem

Describe the bug When using workflow level environment variables they do not work when I use them to substitute for `jobs.build.name` or `jobs.build.runs-on`. See workflow file below for example: [code block] To Reproduce Steps to reproduce the behavior: 1.- Run the workflow file above to receive the following error: `The workflow is not valid. .github/workflows/dev.yml (Line: 15, Col: 11): Unrecognized named-value: 'env'. Located at position 1 within expression: env.aws_account,.github/workflows/dev.yml (Line: 16, Col: 14): Unrecognized named-value: 'env'. Located at position 1 within expression: env.aws_account` Expected behavior The expected behavior is that using the workflow file above the `build.name` would be `Deploy|cfaittoolsnp` and the `build.runs-on` would be `cfaittoolsnp`. Runner Version and Platform Running latest version of linux self-hosted runner. OS of the machine running the runner? linux (ubuntu 18.04)
