fix: resolve flowtype ESLint plugin error blocking dev setup on Node 20

[lavuchandu169]

Problem

When setting up the project locally on Node 20, running pnpm start fails immediately with:

Failed to load plugin 'flowtype' declared in 'BaseConfig':
Package subpath './lib/rules/no-unused-expressions' is not defined
by "exports" in eslint-plugin-flowtype

This completely blocks the development server from starting, making it
impossible to contribute locally on Node 20.

Root Cause

The eslint-config-react-app package declares a dependency on
eslint-plugin-flowtype, which is incompatible with the version of
ESLint used in this project on Node 20.

Fix

Added a local .eslintrc.js override in packages/typescriptlang-org
that resets the conflicting ESLint configuration, allowing the dev
server to start successfully.

Environment Tested

• Node: v20.20.2
• pnpm: v10.30.3
• OS: macOS (Apple Silicon / arm64)

Result

• pnpm start completes successfully
• Site loads correctly at http://localhost:8000
• No functionality affected
