Replace the scaffolded `tsconfig.json` with `deno.jsonc`

Hi,

I'm setting up a test project with Alosaur to find the Deno equivalent of a Nest.js stack.

When using the CLI, a tsconfig.json is generated. After a quick check with the official documentation, it appears deno.json and deno.jsonc are the default since v1.18 (release notes). Can this be updated?

If you prefer for me to create a pull request, feel free to ask.
