What is the problem you're trying to solve

If I fork the containerd repository and try to build my own release by using "Containerd Release" workflow in the forked repository, I have a problem.

This part checks out the revision to be built, but since containerd/containerd is specified as the repository, the checkout fails.

Describe the solution you'd like

Would you mind removing the line? (including in the branches for the currently supported releases (i.e. release/1.3 and release/1.4))
There is a section that checks the signature of the revision, but no repository is specified there.

Additional context
