When using some monorepo-related tools (like [changesets](https://github.com/changesets/changesets)), the produced tags have a special format that includes `@` character. For example, a `foo` package on a monorepo will produce Git tags looking like `foo@1.0.0` if using changesets. When used in combination with `actions/attest-build-provenance`, the action was not properly re-crafting the tag in `buildSLSAProvenancePredicate` because it was always splitting the workflow ref by `@` and taking the second element. This result in this error on CI: ``` Error: Error: Failed to persist attestation: Invalid Argument - values do not match: refs/tags/foo != refs/tags/foo@1.0.0 - https://docs.github.com/rest/repos/repos#create-an-attestation ```` This PR slightly update the logic there, and rather take "everything located after the first '@'". This shouldn't introduce any breaking change, while giving support for custom tags. I've added the corresponding test case, it passes, however I couldn't successfully run the full test suite (neither on `main`). Looking forward for CI outcome. Thanks in advance for the review 🙏.
