chore: remove holesky configs and update tests to hoodi

[KoxyG]

Motivation

Replace deprecated Holesky network support with Hoodi testnet configuration. Hoodi is a new Ethereum testnet that will serve as a replacement testnet, and this change updates Lodestar to support the new network configuration.

Description

This PR removes Holesky network configuration and replaces all references with Hoodi testnet support. Changes include:

• Removed packages/cli/src/networks/holesky.ts network file
• Removed packages/config/src/chainConfig/networks/holesky.ts chain config
• Updated all network references from "holesky" to "hoodi" across CLI, config, and test files
• Added Hoodi network configuration with proper chain parameters, genesis data, and bootnodes
• Updated default environment configuration
• Updated unit tests to reflect the network change

Closes ##8615

Summary of Changes

Hello @KoxyG, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request undertakes a significant refactoring to deprecate and remove all traces of the Holesky testnet, replacing them with the Hoodi testnet. This change involves deleting specific network definition files, updating network lists and types, and modifying test cases and command examples to reflect the new Hoodi network. The overall purpose is to streamline the codebase by removing outdated network configurations and integrating the current testnet strategy.

Highlights

• Holesky Network Deprecation: The Holesky testnet configuration and all its associated files have been completely removed from the codebase, indicating its deprecation.
• Hoodi Network Integration: All references to 'holesky' across various configuration files, type definitions, and utility functions have been systematically replaced with 'hoodi', establishing Hoodi as the new target testnet.
• Test Suite Updates: Unit tests related to network configurations, paths, and interop comparisons have been updated to align with the transition from Holesky to Hoodi, ensuring test accuracy for the new network.

Code Review

This pull request removes the 'holesky' testnet configuration and references from the codebase. The changes are mostly mechanical, involving file deletions and find-and-replace operations. The tests have been updated to use the 'hoodi' testnet where 'holesky' was previously used. The changes appear correct and consistent with the goal of removing the 'holesky' network. I've added one comment to improve the documentation in default.env.

Please also make sure you look at all the unit tests that still depend on holesky configs. Example:

Hi @philknows @nflaig I just made the changes

[nflaig]

Great job @KoxyG, looks pretty good

[nflaig]

there are two more places we should update to hoodi

lodestar/packages/flare/src/cmds/selfSlashAttester.ts

Line 22 in 1f2a3a4

command: "self-slash-proposer --network holesky",

(also feel free to correct the example command)

lodestar/packages/era/src/era/util.ts

Line 13 in 1f2a3a4

/** CONFIG_NAME field of runtime config (mainnet, sepolia, holesky, etc.) */
