chore: bump GitHub Actions to latest major versions

[Copilot]

Update all uses: action references across .github/workflows/build.yml, deploy.yml, and release.yml to their current latest major versions.

Version bumps

Action	Old	New
actions/checkout	@v4	@v6
actions/setup-java	@v4	@v5
actions/cache	@v4	@v5
actions/upload-artifact	@v4	@v6
docker/metadata-action	@v5	@v6
docker/setup-qemu-action	@v3	@v4
docker/setup-buildx-action	@v3	@v4
docker/build-push-action	@v5	@v7
docker/login-action	@v3	@v4

softprops/action-gh-release@v2 is already at the latest major version — left unchanged.

Original prompt

Update all uses: action references in all workflow files under .github/workflows/ to their latest versions.

The following actions need to be updated across all three workflow files (build.yml, deploy.yml, release.yml):

Action	Current Version	Latest Version
actions/checkout	@v4	@v6
actions/setup-java	@v4	@v5
actions/cache	@v4	@v5
actions/upload-artifact	@v4	@v6
docker/metadata-action	@v5	@v6
docker/setup-qemu-action	@v3	@v4
docker/setup-buildx-action	@v3	@v4
docker/build-push-action	@v5	@v7
docker/login-action	@v3	@v4

softprops/action-gh-release@v2 is already at the latest major version and does NOT need to be changed.

Files to modify:

1. .github/workflows/build.yml — update actions/checkout, actions/setup-java, actions/cache, actions/upload-artifact, docker/metadata-action, docker/setup-qemu-action, docker/setup-buildx-action, docker/build-push-action
2. .github/workflows/deploy.yml — update actions/checkout, actions/setup-java, actions/cache, actions/upload-artifact
3. .github/workflows/release.yml — update actions/checkout, actions/setup-java, actions/cache, docker/metadata-action, docker/setup-qemu-action, docker/setup-buildx-action, docker/build-push-action, docker/login-action, softprops/action-gh-release stays at @v2

Important:

• Only change the version tags (e.g. @v4 → @v6), do NOT modify any other part of the workflow files.
• Make sure every occurrence of the listed actions is updated in every file.

The following is the prior conversation context from the user's chat exploration (may be truncated):

Assistant:

Let me first check the current workflow files to see all the uses references, then look up the latest versions.

Assistant: Now let me check the latest versions of all the GitHub Actions used in these workflows.

Assistant: Now I have all the information needed. Let me create a summary of the updates and create the PR.

Here's what needs to be updated across all 3 workflow files:

Action	Current Version	Latest Version
actions/checkout	v4	v6
actions/setup-java	v4	v5
actions/cache	v4	v5
actions/upload-artifact	v4	v6
docker/metadata-action	v5	v6
docker/setup-qemu-action	v3	v4
docker/setup-buildx-action	v3	v4
docker/build-push-action	v5	v7
docker/login-action	v3	v4
softprops/action-gh-release	v2	v2 (already latest)
