ci: pin GitHub Actions runners to ubuntu-24.04

[redhat-chai-bot]

GitHub will switch the ubuntu-latest runner label to Ubuntu 26.04 on October 19, 2026. Workflows using ubuntu-latest may break when toolchains, system packages, and default versions change on the new image.

This PR pins all runs-on: ubuntu-latest references in GitHub Actions workflows to ubuntu-24.04 to prevent unexpected breakage from the runner image change.

Changes

All runs-on: ubuntu-latest entries in .github/workflows/ have been replaced with runs-on: ubuntu-24.04. No other workflow logic or configuration has been changed. Workflows that already specified ubuntu-24.04 are untouched.

Summary

This change updates CI configuration in .github/workflows/ci.yaml, .github/workflows/push-to-main.yaml, and .github/workflows/release.yaml. It replaces ubuntu-latest with ubuntu-24.04 for all nine listed jobs. Other workflow logic is unchanged.

• Affected areas: .github/workflows/ only. No changes affect libs/ui-components/, libs/types/, libs/i18n/, libs/cypress/, apps/standalone/, apps/ocp-plugin/, proxy/, or packaging/.
• Impact: The change pins the runner image for CI jobs, including container-build and integration-test jobs. It does not change container-build or E2E test logic.
• Cross-cutting implications: No shared UI component or platform-specific app code changed. The effect is limited to the GitHub Actions runner environment.

Risk classification

risk:ask applies. The labeling instructions classify semantic CI changes as risk:ask, and changing runs-on is explicitly listed as semantic. risk:ship does not apply because it permits only comment and formatting changes to workflows. risk:show does not apply because the semantic CI change matches an explicit risk:ask trigger.
