Backport of actions: allow invoke only on local execution while TFC adds support into v1.14

[github-actions]

Backport

This PR is auto-generated from #37653 to be assessed for backporting due to the inclusion of the label 1.14-backport.

The below text is copied from the body of the original PR.

---

This PR just returns an error early if a user tries to invoke actions with a cloud backend. TFC hasn't been updated yet, and Terraform crashes if this is attempted. With this we just get an error message instead of a crash, and we can remove this once TFC is up to date.

Target Release

1.14.x
