cargo generate uses {{CRATE_NAME}} but does not populate correctly in README

[Oghma]

The README includes badges that reference {{CRATE_NAME}}, but the variable is not being replaced. As a result, the generated README shows empty crate links:

[![Crates.io](https://img.shields.io/crates/v/.svg)](https://crates.io/crates/)  
[![Documentation](https://docs.rs//badge.svg)](https://docs.rs/)  

Expected behavior: {{CRATE_NAME}} should be replaced with the actual crate name during template generation or ignored.
