Fix failing integration test: update playwright tool count and naming format

[Copilot]

TestPlaywrightMCPServer/ToolsRegistered was failing because the test contained stale hard-coded expectations that no longer match the current mcp/playwright image behavior.

Changes

• Tool count: Updated expected count from 22 → 21 to match the tools the current playwright image actually registers
• Tool name separator: Updated from triple-underscore (playwright___browser_close) → dash (playwright-browser_close) to match the current gateway naming convention

// Before
if !strings.Contains(stderrStr, "Registered 22 tools from playwright") &&
    !strings.Contains(stderrStr, "Registered tool: playwright___browser_close") {

// After
if !strings.Contains(stderrStr, "Registered 21 tools from playwright") &&
    !strings.Contains(stderrStr, "Registered tool: playwright-browser_close") {
