CLI: Add --no-dev option to init

[fastfrwrd]

Closes #25510

What I did

adds optional --dev and --no-dev options to the storybook init CLI.

• this option allows users of the init CLI to force the init workflow to conclude before running the dev server after initialization.
• this is still the default behavior when storybook init is run in CI or in the Storybook sandbox, although the option can also be used to override the behavior in those cases as well.
  • unfortunately, because Commander automatically initializes the boolean with the default value of true, and I couldn't override the default value from the negated --no-dev option, I was forced to add a --dev option with the correct defaults. see --no is bugged with default arguments tj/commander.js#2068 (comment) and Adding negative option makes Commander.js to return "true" when option is not specified tj/commander.js#979 for more on this topic.

as far as I could tell, there aren't automated tests for the init CLI?

Manual testing

Ran the sandbox as described. Additionally, I ran the following against a fresh create-next-app to test that the flag works as expected, that the default behaviors still worked as expected, and that the intersection of the defaults and the flags also worked.

$ > npx create-next-app

$ > node ../storybook/code/lib/cli/bin/index.js init
$ > node ../storybook/code/lib/cli/bin/index.js init --dev
$ > node ../storybook/code/lib/cli/bin/index.js init --no-dev

$ > CI=true node ../storybook/code/lib/cli/bin/index.js init
$ > CI=true node ../storybook/code/lib/cli/bin/index.js init --dev
$ > CI=true node ../storybook/code/lib/cli/bin/index.js init --no-dev

$ > IN_STORYBOOK_SANDBOX=true node ../storybook/code/lib/cli/bin/index.js init
$ > IN_STORYBOOK_SANDBOX=true node ../storybook/code/lib/cli/bin/index.js init --dev
$ > IN_STORYBOOK_SANDBOX=true node ../storybook/code/lib/cli/bin/index.js init --no-dev
