Allow added components to use relative import paths instead of aliases

[rsolomon]

Problem or use case

I totally understand the general desire to use import aliases, but it would also be great if we could at least opt-out and have components generated via untitledui@latest add use relative imports.

#95 suggested that some version at least supported this accidentally, but as of today it appears that an alias is required for the command to successfully execute.

Proposed solution

Allow the CLI user to skip the What is the import alias for your project? question, resulting in a generated component and related files with relative imports instead of the default @/.

Alternatives considered

1. Refactor an entire monorepo to use aliased imports
2. Allow aliased imports, creating a stylistic inconsistency within the codebase
3. Refactor after component creation to use relative imports, either manually or via codeshift
