GitHub deprecated the Node.js 20 runtime for actions. Each workflow run now ends with this warning:

  Node.js 20 is deprecated. The following actions target Node.js 20
  but are being forced to run on Node.js 24: actions/checkout@v4,
  actions/setup-go@v5.

Update all workflows to the first major versions that run on Node.js 24 by default:

  actions/checkout           v4 -> v7
  actions/setup-go           v5 -> v7
  actions/setup-java         v3 -> v6
  actions/upload-artifact    v4 -> v7
  actions/download-artifact  v4 -> v8

golangci/golangci-lint-action@v9 already runs on Node.js 24, so it does not change.

No workflow input changes are necessary:

• All artifacts are uploaded and downloaded by name, so the path change for downloads by ID (download-artifact v5) does not apply. No upload uses "archive: false", so the direct-upload changes in upload-artifact v7 and download-artifact v8 do not apply.
• No workflow uses pull_request_target or workflow_run, so the new fork checkout block in checkout v7 does not apply. No step uses the git credentials that checkout keeps after the clone.
• The container jobs (Rocky 8/9/10, Ubuntu 22.04/24.04) already run these actions on Node.js 24 because of the forced upgrade, so the runtime is already known to work there.
