[BUG] documentation not upto date with `ion`

[psteinb]

Describe the bug

The Comonicon.jl docs say, that one could/should use ion to create a project repo. The following call doesn't work with ion 0.1.12:

ion new Demo --template=comonicon

the comonicon template simply doesn't exist.

Version of the package:

To Reproduce
Steps to reproduce the behavior:

1. Install ion from here https://github.com/Roger-luo/Ion/releases/tag/v0.1.21 (I used ion-v0.1.21-x86_64-unknown-linux-musl.tar.gz)
2. Unpack ion
3. Run the cmd ion new Demo --template=comonicon
4. Get the error message:

thread 'main' panicked at 'Template file not found: /home/steinb95/.config/ion/resources/templates/comonicon/template.toml', src/ion/blueprints/template.rs:9:30
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Expected behavior
No error at all.
