fix: update broken Playwright MCP Bridge store links

[yanCode]

Summary

• replace the outdated Playwright MCP Bridge Chrome Web Store URL in the English README section
• replace the same outdated URL in the Chinese README section
• point all four references to the same Chrome Web Store listing referenced by the official Microsoft Playwright MCP extension documentation

Reference

• Microsoft Playwright MCP extension documentation: https://github.com/microsoft/playwright-mcp/blob/main/packages/extension/README.md

Verification

• confirmed the old URL (kldoghpdblpjbjeechcaoibpfbgfomkn) redirects to an invalid empty-title / unavailable page
• confirmed the updated URL (mmlmfjhmonkocbjadbfplnigmagldckm) resolves to the Playwright MCP Bridge listing
• confirmed the updated URL matches the Chrome Web Store link currently referenced in the Microsoft documentation above

Context

The previously linked Chrome Web Store page appears unavailable and shows the same failure reported by users (for example, "This item is not available").
