Add an option to automatically install dependencies.

[btea]

Please describe

After the project initialization is completed, add the option of whether to automatically install dependencies. If the user selects true, the dependencies will be installed directly.

Additional context

Because the project we initialize must install dependencies before it can run, if you can directly choose automatic installation, you can omit the manual installation command operation.

I don't really miss this, but why not. I'm wondering if it's worth adding another question when generating the app.
Also, which package manager would be use if the user wants to install the deps? npm in all cases or do we ask which one?

Lines 657 to 664 in 0b1d1d4

	const userAgent = process.env.npm_config_user_agent ?? ''
	const packageManager = /pnpm/.test(userAgent)
	? 'pnpm'
	: /yarn/.test(userAgent)
	? 'yarn'
	: /bun/.test(userAgent)
	? 'bun'
	: 'npm'

I think it can be hit according to the code.
