PowerShell Core 7 on GitHub Actions?

Once PowerShell Core 7 comes out of release candidate when could we expect that to become the new default for the pwsh shell?

I tried installing the release candidate: https://github.com/casz/test-powershell-github-action/blob/master/.github/workflows/action.yml

But seems I need to point directly to the install location.

Perhaps you could consider installing the pwsh-rc/pwsh-preview shell?
