fix(ci): Remove redundant checkout step in release workflow

The `release` job only uploads artifacts that were built in a prior `build` job. A separate `checkout` step is not needed as the artifacts already contain the necessary files. Removing this step streamlines the workflow and avoids unnecessary fetching of the repository history.
