Rename build job and add OIDC token permissions

Renamed the `build` job in `Release.yml` to `build-and-publish`
to better reflect its purpose. Added a `permissions` section
to enable `id-token: write`, allowing the job to issue GitHub
OIDC tokens for authentication. Retained `windows-latest` as
the runner environment and included the `actions/checkout@v4`
step for repository code checkout.
