Fix buildx install flag and enhance release workflow with manual dispatch support

[Copilot]

Mirrors fixes from devops-infra/action-commit-push (ea9308d, 67ef619, f01d240): removes redundant install: true from buildx setup, exposes version:tag-release as a non-internal task, and adds workflow_dispatch support with duplicate-tag protection to the release workflow.

Buildx fix (auto-create-pull-request.yml, auto-create-release.yml, cron-check-dependencies.yml)

• Removed with: install: true from docker/setup-buildx-action@v3 — redundant with current action defaults

Taskfile.cicd.yml

• Removed internal: true from version:tag-release so it can be called directly from workflows

Release workflow (auto-create-release.yml)

• Added workflow_dispatch trigger
• Updated job if: to pass on manual dispatch in addition to merged release PRs
• Create and push git tags step now captures REL_VERSION first, checks remote for existing tag, and either skips gracefully (manual dispatch) or hard-fails (automated) on duplicate:

full_remote_sha="$(git ls-remote --tags origin "refs/tags/${REL_VERSION}" 2>/dev/null | awk '{print $1}' || true)"
if [ -n "${full_remote_sha}" ]; then
  if [ "${GITHUB_EVENT_NAME}" = "workflow_dispatch" ]; then
    echo "ℹ️ INFO: Full tag '${REL_VERSION}' already exists; skipping tag creation."
  else
    echo "❌ ERROR: Full tag '${REL_VERSION}' already exists; aborting" >&2
    exit 1
  fi
else
  task version:tag-release
fi

Pull request overview

This pull request mirrors fixes from the devops-infra/action-commit-push repository to enhance the release workflow with manual dispatch support and clean up redundant Docker Buildx configuration. The changes remove deprecated install: true parameters from buildx setup, expose a previously internal task for direct workflow use, and add duplicate tag protection that behaves differently for manual vs automated releases.

Changes:

• Removed redundant install: true from docker/setup-buildx-action@v3 across three workflow files (the action now installs by default)
• Exposed version:tag-release task by removing internal: true flag to enable direct workflow invocation
• Added workflow_dispatch trigger to release workflow with smart duplicate-tag handling that gracefully skips for manual runs but fails for automated ones

The environment variable GITHUB_EVENT_NAME is not available by default in shell scripts. GitHub Actions exposes this value through the context variable github.event_name, but it needs to be explicitly passed to the shell environment. Add GITHUB_EVENT_NAME to the env section of this step with the value from the context.
