Add automated functional acceptance testing for Web Config with webship-js (Playwright + Cucumber-js) and have the default recipe install all bundled configuration modules

Problem/Motivation

The Web Config module had no automated functional
acceptance test coverage, so there was no way to confirm that a fresh
install actually enables the bundled configuration-management modules and
that their admin screens load.

While verifying this, two defects surfaced:

• The webconfig/default recipe only installed a subset of
  the bundled modules. config_split, config_ignore,
  config_inspector and config_rewrite were required
  in composer.json (and advertised in the README) but were never
  enabled on install.
• webconfig.info.yml declared module dependencies and
  used the recipe, and its description line contained a stray
  trailing quote.

Proposed resolution

• Expand recipes/default/recipe.yml to install every bundled
  module — config, config_update,
  config_update_ui, config_filter,
  config_split, config_ignore,
  config_inspector, config_rewrite,
  config_import_single — and import their configuration.
• Make the recipe the single source of truth for installation: remove the
  module dependencies from webconfig.info.yml and fix
  the description typo.
• Add a webship-js (Playwright + Cucumber-js) BDD test
  suite under tests/ with shared config (cucumber.js,
  playwright.config.ts, role-based test users, CMS selectors).
• Add a GitLab CI webship-js-test job to
  .gitlab-ci.yml that installs Drupal + the module, provisions
  Node 20 and Playwright Chromium, and runs the suite.

Functional coverage (22 scenarios, 89 steps — all passing)

• Login fixtures for Webmaster, Content editor and Authenticated user.
• Recipe enables every bundled module; each config admin route is reachable.
• Core configuration Synchronize / Import / Export pages.
• Configuration Update Manager Updates report.
• Configuration Inspector overview (/admin/reports/config-inspector).
• Configuration Split list and add form.
• Config Ignore settings form.
• Single configuration import and export forms.
• End-to-end single export — selecting a config item renders its YAML.
• Access control: anonymous and authenticated users are denied.
