chore: update playwright and @web/test-runner dependencies with comprehensive test refactoring (#5578)

This pull request represents a comprehensive update to testing infrastructure and dependencies across the entire Spectrum Web Components codebase. The changes include major dependency updates for Playwright and @web/test-runner packages, extensive test refactoring for improved reliability and maintainability, and enhanced CI/CD configurations.

Major Dependency Updates
Playwright:

Updated Docker image in CI from mcr.microsoft.com/playwright:v1.44.0 to v1.53.1
Updated @playwright/test version from ^1.44.0 to ^1.53.1
@web/test-runner Ecosystem:

Updated @web/test-runner from ^0.18.3 to ^0.20.2 across multiple packages
Updated @web/test-runner-junit-reporter from ^0.7.2 to ^0.8.0
Updated @web/test-runner-playwright from ^0.11.0 to ^0.11.1
Updated @web/test-runner-visual-regression from ^0.9.0 to ^0.10.0
Updated wireit from ^0.14.3 to ^0.14.12
Infrastructure Improvements
CI/CD Configuration:

Enhanced CircleCI configuration with updated Docker images and improved parallelism
Added new Chromium memory testing configuration (web-test-runner.config.ci-chromium-memory.js)
Updated GitHub Actions workflows for better coverage reporting
Added concurrency settings across all browser test configurations
ESLint and Code Quality:

Expanded ESLint coverage to include **/stories/*.ts files
Updated ESM import syntax from assert { type: 'json' } to with { type: 'json' }
Fixed import paths for visual regression commands
Dependency Management:

Added comprehensive patching system documentation in CONTRIBUTING.md
Created Yarn patches for @web/test-runner-playwright and @web/test-runner-visual-regression
Removed legacy patch-package dependency in favor of Yarn 4's built-in patching
Comprehensive Test Suite Refactoring (132 files affected)
Testing Helper Functions:

Refactored mouse interaction helpers: sendMouse → mouseClickOn, mouseClickAway, mouseMoveOver, mouseMoveAway
Enhanced keyboard interaction helpers: sendKeys → sendTabKey, sendShiftTabKey
Improved focus management with waitForFocusEvent and waitForElementReady helpers
Added resetMouse functionality for better test isolation where I could
Component Test Improvements:

Accordion: Enhanced keyboard navigation testing and memory management (accordion-memory.test.ts)
Action Components: Improved mouse and keyboard event handling across action-bar, action-button, action-group, and action-menu
Color Components: Standardized testing patterns across color-area, color-handle, color-loupe, color-slider, and color-wheel
Form Components: Enhanced accessibility testing for combobox, number-field, radio, textfield, and switch components
Layout Components: Improved interaction testing for tabs, table, sidenav, and split-view
Overlay System: Comprehensive refactoring of overlay, dialog, tooltip, and picker components with enhanced trigger management
Navigation Components: Updated menu, breadcrumbs, and top-nav testing patterns
Browser Compatibility:

Added WebKit and Firefox-specific test skips for flaky tests
Enhanced cross-browser event handling
Improved timeout management for CI stability
Code Quality Improvements
Error Handling:

Added ResizeObserver loop error suppression in tests
Improved language resolution with fallback to 'en-US' in LanguageResolution.ts
Enhanced error boundaries in component lifecycle methods
Performance Optimizations:

Streamlined test execution with better helper functions
Reduced redundant DOM queries and event handling
Optimized fixture creation patterns across all components
Story and Documentation Updates
Storybook Enhancements:

Added triggered-by attributes for better overlay interaction documentation and reduce browser logs
Impact Statistics:

Improved test reliability and reduced flakiness across all components
Better developer experience with enhanced testing helpers
Modernized ESM import syntax and dependency management
