Exports package.json

[tylergaw]

This adds an entry in package.json to export package.json.

Why?

I'm using addon-svelte-csf in a monorepo where I need to find the absolute path of a package in .storybook/main.js. A simplified version:

addons: [
  dirname(require.resolve(join('@storybook/addon-svelte-csf', 'package.json')))
]

What happens currently?

Without the exported package.json, we hit an error attempting to get it

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './package.json' is not defined by "exports"

Is this normal?

I think so. Looking at other official addons, it looks common to export package.json. Examples:

• controls https://github.com/storybookjs/storybook/blob/next/code/addons/controls/package.json#L37
• addon-links https://github.com/storybookjs/storybook/blob/next/code/addons/links/package.json#L39C5-L39C39
• a11y https://github.com/storybookjs/storybook/blob/next/code/addons/a11y/package.json#L38

Again, this seems OK to do, but I am a little hazy on how the exports setup is supposed to work, so this may not be the right way to do this.
