_No response_

### Is this related to another service?

_No response_

### Describe the feature you'd like to request

when attempting to create a new amplify project using the cli one cannot use hyphens such as pauls-project

when using the Web Console, you can.

### Describe the solution you'd like

can we get hyphens added to the amplify init regex please?

thanks.

### Describe alternatives you've considered

manually creating the app in the console every time.. seems a bit annoying.

### Additional context

_No response_

### Is this something that you'd be interested in working on?

- [ ] 👋 I may be able to implement this feature request

### Would this feature include a breaking change?

- [ ] ⚠️ This feature might incur a breaking change

Start by locating the project-name validation regex used by the amplify init flow, then reproduce the rejection with a hyphenated name such as pauls-project. Done means the CLI accepts hyphenated project names consistently with the Web Console and the relevant validation behavior is covered by tests, if present.
