The manner of gh-oidc is outdated

Issue

When I used the gh-oidc module, I got the error. I think the manner of GitHub OIDC was updated.

ERROR: gcloud crashed (OAuthError): ('Error code invalid_grant: Specified identity issuer https://token.actions.githubusercontent.com not found in the configured identity providers.', '{"error":"invalid_grant","error_description":"Specified identity issuer https://token.actions.githubusercontent.com not found in the configured identity providers."}')

Though I haven't completely understood the specification of GitHub OIDC, google_iam_workload_identity_pool_provider.oidc.issue_uri should be https://token.actions.githubusercontent.com.

https://github.com/terraform-google-modules/terraform-google-github-actions-runners/blob/v1.1.0/modules/gh-oidc/main.tf#L35-L38

  oidc {
    issuer_uri        = "https://token.actions.githubusercontent.com"
  }
