Add 2XLarge to 6XLarge warehouse sizes to pricing documentation

[Copilot]

Summary

This PR adds pricing information for larger warehouse sizes (2XLarge through 6XLarge) to the Databend Cloud pricing documentation in both English and Chinese.

Changes

Updated the warehouse pricing tables in:

• docs/fragment/03-pricing-en.md (English documentation)
• docs/fragment/03-pricing-cn.md (Chinese documentation)

New Warehouse Sizes Added

Size	Hourly Cost (Personal)	Hourly Cost (Business)	Per-Second Cost (Personal)	Per-Second Cost (Business)
2XLarge	$32.00	$48.00	$0.008888889	$0.013333333
3XLarge	$64.00	$96.00	$0.017777778	$0.026666667
4XLarge	$128.00	$192.00	$0.035555556	$0.053333333
5XLarge	$256.00	$384.00	$0.071111111	$0.106666667
6XLarge	$512.00	$768.00	$0.142222222	$0.213333333

The pricing follows the established doubling pattern where each tier costs 2× the previous tier. Per-second costs are calculated by dividing the hourly rate by 3600 seconds, consistent with existing pricing methodology.

Chinese pricing maintains the 3:1 USD-to-CNY conversion rate that was established in the original pricing structure.

Testing

• Verified the doubling pattern is consistent across all tiers
• Confirmed per-second cost calculations are accurate (hourly cost ÷ 3600)
• Validated currency conversion consistency between English and Chinese versions
• Checked markdown table formatting renders correctly
