📝[Docs]: Replace Python Lint Instructions with ESLint + TypeScript Setup

[sheikhlimon]

Is there an existing issue for this?

• I have searched the existing issues

Issue Description

The page community/understand-lint-check.md still references Python linting tools (flake8, black, mypy, etc.).
recode hive uses TypeScript + React + Docusaurus, so the guide should describe our actual linting workflow.
Same for about section too in repo

Suggested Change

Linting & Formatting Tools

• Linting: eslint
• Formatting: prettier
• Type Checking: tsc

Example Commands

npm install
npm run lint
npm run lint:fix
npm run typecheck
npm run format
npm run build

Rationale

• The Python instructions are obsolete.
• Keeps contributor guidelines accurate for the TypeScript / React stack.
• Reduces onboarding confusion and ensures consistent code quality checks.

Urgency

Medium

Record

• I have read the Contributing Guidelines
