support Bun

[Songmu]

Thank you for developing such wonderful OSS.

When I ran create-create-app using Bun, the following error occurred.

$ bun create create-app hoge                                                       (node:49250) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.
(Use `node --trace-deprecation ...` to show where the warning was created)

# Environment
- create-create-app: 7.3.0

If you think this is a bug, please report at https://github.com/uetchy/create-create-app/issues along with the information above.

This is because create-create-app does not support Bun as a package manager.

In the pull request, I supported Bun and added error handling within the switch statement to make the error message easier to understand.

It is up to you to decide whether or not we should support Bun.
