ci(common): mergify e2e tests workflow

[eudelins-zama]

Closes https://github.com/zama-ai/fhevm-internal/issues/684

Forked from #1076.

I tried another approach, using workflow_call instead of workflow_dispatch for docker build workflows.
It felt more "natural", and avoid the need to poll for dispatched workflows using github-script.
But it required some boilerplate in these workflows.

I tested the test-suite-orchestrate-e2e-test.yml by commenting some if conditions to trigger/disable the workflows I wanted.
But now the final test would be to add this PR to the merge queue. So I guess we first need to review it, otherwise it could be merged

Pull request overview

This PR introduces a new CI workflow orchestration system for running E2E tests in Mergify merge queue environments. The changes enable Docker builds and tests to be triggered via workflow_call, allowing the new orchestrator workflow to coordinate builds across multiple components and then run E2E tests with the built images.

Key changes:

• New orchestrator workflow that builds all components and runs E2E tests for merge queue PRs
• Refactored existing Docker build workflows to support both direct triggers and workflow_call
• New dedicated E2E test workflow for merge queue with custom component version handling
• Updated actionlint configuration to suppress specific warnings
• Package-lock.json peer dependency updates
