Jttps://codecov.io/env doesn't support GitHub Actions

From what I can tell https://codecov.io/env does not support GitHub Actions yet. Hopefully this will be a quick fix. I added the following to a local file and it said GitHubAction detected at least.

elif [ "$CI" = "true" ] && [ "$GITHUB_ACTIONS" != "" ];
then
  add "GITHUB_ACTION"
  add "GITHUB_WORKFLOW"
  add "GITHUB_RUN_ID"
  add "GITHUB_RUN_NUMBER"
  add "GITHUB_ACTION"
  add "GITHUB_ACTIONS"
  add "GITHUB_ACTOR"
  add "GITHUB_REPOSITORY"
  add "GITHUB_EVENT_NAME"
  add "GITHUB_EVENT_PATH"
  add "GITHUB_WORKSPACE"
  add "GITHUB_SHA"
  add "GITHUB_REF"
  add "GITHUB_HEAD_REF"
  add "GITHUB_BASE_REF"

Cheers,

Hi @altendky, thanks for pointing this out. I have updated the env file with other CIs here, but it already has variables for GitHub Actions here. We will look into deploying this next week.
