Set default value for githubToken?

[anatawa12]

Context

In the document, we need to set githubToken: ${{ secrets.GITHUB_TOKEN }} to see test results. However, it's not necessary for users I think.

Suggested solution

If you set ${{ github.token }} (which is equivalent to ${{ secrets.GITHUB_TOKEN }}) as a default value for githubToken, We don't need to set github token manually.

Additional details

${{ github.token }} as a default value is used in many official actions. For example, actions/checkout
