CI: consolidate Ubuntu 22.04/24.04 workflows into single matrix-drive…

[tuhaihe]

…n file

Replace two separate Ubuntu DEB CI workflow files with one matrix-driven workflow that runs build + test across Ubuntu 22.04 and 24.04.

Key changes:

• Rewrite: .github/workflows/build-deb-cloudberry.yml
• Remove: build-deb-cloudberry-ubuntu24.04.yml
• PR trigger: both Ubuntu versions now run on every PR (was only 22.04 before; 24.04 only triggered on push to main)
• Remove scheduled cron trigger (push + PR coverage is sufficient)
• Build/deb-install-test jobs use strategy.matrix.ubuntu_version ['22.04', '24.04']; test-deb job receives ubuntu_version via prepare-test-matrix-deb cross-product expansion
• Container images dynamically resolved via matrix.ubuntu_version (cbdb-build-ubuntu${version}-latest)
• Job naming: Ubuntu 22.04 keeps original names (no suffix) for .asf.yaml compatibility; Ubuntu 24.04 appends "(Ubuntu 24.04)"
• Artifact names consistently suffixed with -ubuntu${version}
• Fix: remove broken matrix.name reference in deb-install-test artifact upload (was referencing a non-existent matrix axis)

Now it's ready to be reviewed. It will take a similar amount of time to run all tests compared to Ubuntu 22.4/24.04 separately, but it also will exceed ~10 minutes if some tests fail. I think it's not too long, so we can accept.

Pull request overview

Consolidates the DEB CI workflows for Ubuntu 22.04 and 24.04 into a single matrix-driven GitHub Actions workflow, so both Ubuntu versions run build + install tests + test matrix consistently on PRs and pushes.

Changes:

• Adds an ubuntu_version workflow_dispatch input and expands the test matrix to cross-join selected tests with selected Ubuntu versions.
• Converts build-deb, deb-install-test, and test-deb to use strategy.matrix.ubuntu_version and version-suffixed artifact naming.
• Removes the dedicated Ubuntu 24.04 workflow file.
