b3cd48228b add detailed errors (#2994)
# Objective

- Improve error descriptions and help understand how to fix them
- I noticed one today that could be expanded, it seemed like a good starting point

## Solution

- Start something like https://github.com/rust-lang/rust/tree/master/compiler/rustc_error_codes/src/error_codes
- Remove sentence about Rust mutability rules which is not very helpful in the error message

I decided to start the error code with B for Bevy so that they're not confused with error code from rust (which starts with E)


Longer term, there are a few more evolutions that can continue this:
- the code samples should be compiled check, and even executed for some of them to check they have the correct error code in a panic
- the error could be build on a page in the website like https://doc.rust-lang.org/error-index.html
- most panic should have their own error code
