docs: add ERC-4337 EntryPoint v0.8 support (#1180)

* docs: add ERC-4337 EntryPoint v0.8 support to low-level infra APIs

Add v0.8 as a supported EntryPoint version across bundler docs, FAQs,
OpenRPC specs, shared component schemas, and revert codes reference.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: add UserOperationV08 schema to _shared_wallets components

The bundler spec references _shared_wallets/components.yaml, not
_shared/components.yaml. Add the v0.8 schemas to the correct file
to fix OpenRPC spec generation.

* docs: set v0.8 EntryPoint address to 0x4337084D9E255Ff0702461CF8895CE9E3b5Ff108

* docs: reuse v0.7 schemas and revert codes for v0.8

v0.7 and v0.8 share the same UserOperation shape and revert codes.
Instead of duplicating, rename v0.7 titles to "v0.7 / v0.8" and
remove the separate UserOperationV08 schemas and revert codes page.

 ### Which EntryPoint versions are supported?
 
-Versions v0.6 and v0.7 of ERC-4337 are currently supported. If you need support for v0.8, contact [wallets@alchemy.com](mailto:wallets@alchemy.com).

+### Which EntryPoint version should I use?
 
-The latest version of ERC-4337 is v0.7, which introduces optimizations aimed at improving the experience for both developers and end users. These include gas savings for users, optimized data structures, better gas estimation, simplified postOp logic, and structured errors during validation.
+The latest version of ERC-4337 is v0.8, which builds on v0.7 with additional improvements including native support for [EIP-7702](https://eips.ethereum.org/EIPS/eip-7702) account delegation and further gas optimizations.
 
-The appropriate version to use is determined by the smart account for which you are trying to send a userOp. Typically, a smart account is written to be compatible with either v0.6 or v0.7. To determine which version is compatible, look at the smart account’s source code and check the first parameter of the `validateUserOp` function. If it has type `UserOperation`, the account uses v0.6. If the parameter type is `PackedUserOperation`, the account uses v0.7.

 ### When will EntryPoint v0.6 be deprecated?
 
-There is not currently a date set to deprecate support for EntryPoint v0.6 but deprecation is planned sometime in 2026. Ensure that you have migrated to EntryPoint v0.7 by that time.

 The Bundler is a key component in the ERC-4337 stack, responsible for collecting, validating, and bundling UserOperations (UserOps) into transactions that are submitted to the EntryPoint contract on the blockchain. The Bundler APIs provide direct access to high-performance, scalable infrastructure (powered by Rundler), enabling developers to interact with a production-grade ERC-4337 bundler for reliable onchain submission of UserOps.
-These APIs are part of the `@account-kit/infra` library, allowing advanced customization when building smart wallet applications. They follow the standard ERC-4337 JSON-RPC endpoints and support versions v0.6 and v0.7 of the protocol, with optimizations for gas estimation, validation, and error handling to ensure UserOps land efficiently while protecting against attacks.

 For full control, bring your own smart contracts or authentication providers while leveraging the bundler for scalability. If you prefer a higher-level abstraction, use the Wallet APIs or aa-sdk instead.
