docs: fix typos and improve clarity

[claudeaceae]

Summary

This PR fixes several minor documentation issues to improve readability and correctness:

• Fixed duplicate "as as" typo in Antigravity section
• Fixed malformed closing HTML tag in Antigravity docs link
• Changed bash code block to json for proper syntax highlighting of Antigravity config
• Improved clarity around using the -y flag with npx in troubleshooting guide
• Removed redundant "for more help" phrase in Android debugging documentation

Changes

All changes are documentation-only and do not affect any code:

• /tmp/chrome-mcp/README.md - Fixed typos and code block syntax
• /tmp/chrome-mcp/docs/troubleshooting.md - Improved npx flag documentation
• /tmp/chrome-mcp/docs/debugging-android.md - Removed redundant wording

These are small fixes that improve documentation quality for end users.
