v2 CLI: themes are dropped into the `/lib` directory instead of project root

[endigo9740]

Current Behavior

Currently when generating a new v2 Skeleton project using the CLI, themes (maybe only custom themes?) are dropped into th e /src/lib directory.

Expected Behavior

Themes should reside in the root of the project, as they're only ever referenced or imported by the tailwind.config

Steps To Reproduce

1. Create a new v2 Skeleton project using the CLI
2. Select either a preset or custom theme options
3. The theme will be inserted into the /src/lib directory

No response

More Information

Not high priority, but would be a worthwhile change before we sunset Skeleton's v2 CLI.
