[CLI] Revisit Bun support when creating new NestJS project

[ccaspanello]

Is there an existing issue that is already proposing this?

• I have searched the existing issues

Is your feature request related to a problem? Please describe it

Previously there was an issue created for this:
Provide bun as a package manager in the startup menu when we create a new nest project

At the time this was not possible because Bun did not support the decorators. However, this has been worked on (see https://bun.sh/blog/bun-v1.0.3?ref=nooptoday.com#emitdecoratormetadata-used-by-nest-js-typeorm-and-more) and some people are having success running it with Bun.

I would really like to see bun as a first class citizen in the CLI tools, I've been favoring it over npm and yarn

Describe the solution you'd like

Add Bun as an option when running nest new my-project

Teachability, documentation, adoption, migration strategy

Links have been provided above.

What is the motivation / use case for changing the behavior?

Bun is widely used and gaining popularity. It seems reasonable to support it.
