[Dev] Provide easy to follow local setup for dev

[machichima]

Provide easy to follow setup/teardown commands and docs for local development for:

• Whole system (single binary)

Can follow how we setup here: #6840 (comment)

For local development of the whole Flyte system, use the Flyte demo cluster with flytectl: install flytectl, then run flytectl demo start to launch a local k3s cluster with all core components (FlyteAdmin, FlytePropeller, Datacatalog, FlyteConsole, Minio, Postgres). For individual components (e.g., flytekit, flyteconsole), clone the relevant repo, set up a Python virtual environment (for flytekit) or Node.js/yarn (for flyteconsole), and follow the component-specific build and run instructions. See the Development Environment Setup Guide for step-by-step commands and requirements.

For example, to start the whole system:

curl -sL https://ctl.flyte.org/install | bash
export PATH=$PATH:/home/ubuntu/bin # adjust as needed
flytectl demo start

For flytekit development:

git clone https://github.com/flyteorg/flytekit.git
cd flytekit
virtualenv ~/.virtualenvs/flytekit
source ~/.virtualenvs/flytekit/bin/activate
make setup
pip install -e .
