We need to create upgrade handlers for v11 in simd, and configure CI (e2e/ci-e2e-config.yaml and .github/workflows/e2e-upgrade.yaml)

Definition of done:

• Upgrade handlers added to /simapp and modules/light-clients/08-wasm/testing/simapp for v11
• e2e tests configured and working for v10 → v11 (you should run and verify this locally before opening a PR: build a local image and configure a local setup to run e2e - see e2e/README.md for more details and just ask if you run into any trouble)
• CI configured to run v10 → v11 tests in e2e/ci-e2e-config.yaml and .github/workflows/e2e-upgrade.yaml.
