fix: remove broken sub-block-specification redirect

[gakonst]

Problem

Direct links to /protocol/blockspace/sub-block-specification were returning 404, even though:

• The page works when navigated to from the sidebar
• The URL shown in the browser matches the expected path

Root Cause

There was a misconfigured redirect in vocs.config.ts:

{
  source: '/protocol/blockspace/sub-block-specification',
  destination: '/protocol/blockspace/subblock-specification', // ← doesn't exist!
  status: 301,
}

This redirected to a non-existent path (subblock-specification without hyphen), but the actual file is sub-block-specification.mdx (with hyphen).

Fix

• Remove the broken redirect
• Fix the /errors/tx/SubblockNonceKey redirect to point to the correct hyphenated path

Fixes: Direct URL access for the sub-block specification page
