`Beaker new` project should have values in `.gitignore`

[ValarDragon]

Currently a project generated from beaker new counter-dapp has a blank gitignore, this is one step we should automate out!

• [ ] use https://github.com/github/gitignore/blob/main/Rust.gitignore as base
• [ ] add artifacts (for wasm artifacts)
• [ ] add **/state.local.json

yes, will add target and artifacts, and other rust related stuffs then (https://github.com/github/gitignore/blob/main/Rust.gitignore). Let me know if there are more to add!
