Summary

This PR introduces biome-config-godaddy, a new Biome configuration package that provides a fast, Rust-based alternative to our existing ESLint and Prettier configurations. There are two config files provided in this package - a JS version biome.json based on eslint-config-godaddy, and a TS version biome-ts.json based on eslint-config-godaddy-typescript.

Motivation

As JavaScript tooling evolves, teams are seeking faster linting and formatting solutions that maintain the same code quality standards. Biome offers significant performance improvements over traditional ESLint + Prettier setups while providing equivalent functionality. This package enables GoDaddy teams to adopt modern tooling without sacrificing our established coding standards.

Key details

• The majority of the rules were generated automatically with Biome's auto-migration cli tool, ensuring their closest translation between the eslint-config-godaddy rules and their Biome equivalents (also note that this is not a 1:1 mapping, many rules are less precise than in eslint).
• This package requires a very recent version of Biome, which is currently in beta because of the new plugins feature, as well as many newer rules that align with our current eslint equivalents.
• I added a json section to each configuration file to mimic the eslint-plugin-json rules.
• I added the useSingleJsDocAsterisk rule to match Biome's equivalency list.
• The eslint-plugin-mocha is already handled by Biome due to its domain feature, which automatically enables rules that belong to a domain with certain package specific dependencies. Read more about domains here.

Test Plan

I tested this change by ensuring that all rules included could be properly overridden in a consuming project. I tested this by symlinking the configurations locally and using it to extend a configuration file in one of my local projects.
