Handle existing-tag releases in Releases workflow build job

[Copilot]

The Releases workflow’s build job failed when run for tags that already had a GitHub Release, due to a 422 already_exists response from the release API. This update makes that path non-fatal so reruns/manual dispatches on existing tags do not fail the job.

• Workflow behavior change

  • Updated .github/workflows/createZipArchive.yml in the ncipollo/release-action@v1 step to skip release creation when the release already exists for the tag.

• Effect on failure mode

  • Converts duplicate-release attempts from hard failure to safe no-op while still uploading artifacts for new releases.
