Migrate to wp-env v11, require Node 20+, remove lock files (#6)

* Migrate to wp-env v11, require Node 20+, remove lock files

- Bump @wordpress/env from ^10 to ^11
- Add engines.node >= 20 to package.json
- Remove package-lock.json and add lock files to .gitignore
- Update CI to use npm install instead of npm ci

* Accommodate wp-env v11 removing test environment

- Use cli container instead of tests-cli (removed in v11)
- Remove env.tests section from .wp-env.json
- Auto-detect test library path (/wordpress-phpunit or /tmp/wordpress-tests-lib)
- Use --legacy-peer-deps for wp-scripts peer dep on wp-env ^10

* Add @testing-library/dom as explicit dependency

Required when using --legacy-peer-deps since peer deps of
@testing-library/react are not auto-installed.
