Bumps `.github/workflows`, `promu` and UI build container to 1.27. We generally keep the minimum required version (1.26) and these versions exactly one minor version apart. Fixes done via `golanglint-ci run --fix`. Also bumps GOLANGCI_LINT_VERSION. This version is required, since the previous was not compatible with Go 1.27.
