cli: Standardize Rust templates for "anchor init" generated JSON and ignore files

[kshyun28]

These changes improve the style and consistency of generated config files when running anchor init.

Summary of Changes

• For .gitignore and .prettierignore, I removed the empty line on line 1.
• For package.json, I adjusted the indentation tab size to 2, then fixed indentation when using jest.
• For tsconfig.json, I fixed the indentation.

Snippets for generate file changes before and after the fixes are shown below.
