please update README.md to reflect usage of uv, where to download utility, etc...

see https://github.com/SANDAG/Population-Sim for an example

[Eric-Liu-SANDAG]

Funny enough, the Population-Sim instructions are not correct for using uv. You should not be manually activating the environment and calling python main.py. Instead, you should just use uv run main.py, which does all the work of activating the environment (as well as a bunch of other checks) for you.

Please make an issue in all our repositories assigning the issues to myself, Bryce, and/or Kevin noting to add you as the reviewer on the subsequent PRs.

Make sure everyone knows they need to update the README.md and remove the environment.yml file in addition to creating the toml and lock files.
