`create-update-issues` fails when a package is published for the first time

The `create-update-issues` workflow assumes that each package has at least one tag. It fails when we publish a package for the first time.

Example: https://github.com/MetaMask/core/actions/runs/11961716257/job/33349064511

Inspect the `create-update-issues` workflow and the linked example run first, focusing on the assumption that every package already has a tag. Reproduce the workflow for a package being published for the first time; it is done when the workflow completes successfully without an existing package tag.
