Shijie Rao 28e7218c0b feat: linux codesign with sigstore (#7674) ...

### Summary
Linux codesigning with sigstore and test run output at
https://github.com/openai/codex/actions/runs/19994328162?pr=7662.

Sigstore is one of the few ways for codesigning for linux platform.
Linux is open sourced and therefore binary/dist validation comes with
the build itself instead of a central authority like Windows or Mac.
Alternative here is to use GPG which again a public key included with
the bundle for validation. Advantage with Sigstore is that we do not
have to create a private key for signing but rather with[ keyless
signing](https://docs.sigstore.dev/cosign/signing/overview/).

This should be sufficient for us at this point and if we want to we can
support GPG in the future.
