Broken links to EIP-8130 page in beryl/overview.mdx (should point to cobalt)

[teyrebaz33]

Description

docs/base-chain/specs/upgrades/beryl/overview.mdx contains two links pointing to /base-chain/specs/upgrades/beryl/eip-8130, which does not exist. The EIP-8130 ("Native Account Abstraction") page actually lives under the cobalt upgrade path: docs/base-chain/specs/upgrades/cobalt/eip-8130.mdx, and is registered under cobalt in docs.json.

Steps to reproduce

1. Open docs/base-chain/specs/upgrades/beryl/overview.mdx
2. See lines 11 and 48
3. Both links point to /base-chain/specs/upgrades/beryl/eip-8130 → 404

Expected

Links should point to /base-chain/specs/upgrades/cobalt/eip-8130

Suggested fix

Update both links in beryl/overview.mdx to use the correct cobalt path.
