Dash app - rsconnect-python missing and old version of dash

Just wanted to log two potential problems here. The first is that we're using a pretty old version of Dash. The latest now is 3.1.1. Second, the instructions are going to remain referenced using the RS Connect Python CLI, however that's not installed, based on the requirements.txt or pyproject.toml.

Suggestions:

# Update dash
uv add 'dash>=3.1.1'

# Add rsconnect-python to 'dev' group
uv add rsconnect-python --group dev

# New way to deploy with rsconnect and uv
uv export -o requirements.txt --no-hashes --no-dev \
    && uv run rsconnect deploy dash .
