Ignition's Test jobs run golangci-lint with the default linter set, which includes errcheck. The release-notes tool synced by #379 (arriving downstream as coreos/ignition#2352) fails lint with seven unchecked error returns:

• two fmt.Fprintf calls to stdout
• defer file.Close() in readFileSnapshot
• defer os.Remove in finalizeWithOps and atomicReplace
• temporary.Close/os.Remove in writeTemporaryFile's deferred cleanup

This explicitly discards those errors, matching the conventions already used elsewhere in Ignition (_, _ = fmt.Fprintf in internal/main.go, defer func() { _ = ... }() in internal/exec, _ = os.Remove in internal/exec/util). None of these errors have a useful handling path: they are best-effort output writes and best-effort cleanup of temporary files.

Verified by rendering the template and running golangci-lint run (v2.11.3, matching CI) and go test against the rendered output inside the Ignition module: 0 issues, tests pass.

Merging this will update the open coreos/ignition#2352 sync branch automatically via sync.yml, turning its Test (1.25.x)/Test (1.26.x) jobs green.
