New docs: Document eth_getStorageValues JSON-RPC method

[alexandratran]

What docs should be added?

Document the new eth_getStorageValues JSON-RPC method added in besu-eth/besu#10259.

This method is a batched version of eth_getStorageAt. It reads multiple storage slots across one or more accounts in a single call.

Suggested docs updates:

• Add eth_getStorageValues to docs/public-networks/reference/api/index.md, near eth_getStorageAt.
• Include parameters:
  • A storage slots request object that maps each 20-byte address to an array of storage slot keys.
  • A block parameter that accepts a hex block number, a block hash, or supported block tags such as latest.
• Document the result as an object mapping each address to an array of hex storage values in the same order as the requested slots.
• Document limits and important behavior verified in the PR:
  • Maximum total storage slots per request is 1024 across all addresses.
  • Empty requests return -32602 with empty request.
  • Requests over the slot limit return -32602 with too many slots (max 1024).
  • Unknown accounts return zero values for requested slots.
  • If the world state can't be opened, Besu returns WORLD_STATE_UNAVAILABLE.
• Update the block parameter page's list of methods that support a blockHash parameter to include eth_getStorageValues.
