Add readme to errors crate and clean up cargo files (#3125)

# Objective

- Document that the error codes will be rendered on the bevy website (see bevyengine/bevy-website#216)
- Some Cargo.toml files did not include the license or a description field

## Solution

- Readme for the errors crate
- Mark internal/development crates with `publish = false`
- Add missing license/descriptions to some crates

- [x] merge bevyengine/bevy-website#216
