TypeScript type error on imports: "The 'accessible-astro-components' library may need to update its package.json or typings."

[JoshuaKGoldberg]

In a project using a tsconfig.json with "moduleResolution": "Bundler", trying to import from accessible-astro-components gives a TypeScript type error:

Could not find a declaration file for module 'accessible-astro-components'. '/Users/josh/repos/joshuakgoldberg-dot-com/node_modules/.pnpm/accessible-astro-components@2.1.0/node_modules/accessible-astro-components/index.js' implicitly has an 'any' type.
  There are types at '/Users/josh/repos/joshuakgoldberg-dot-com/node_modules/accessible-astro-components/types/index.d.ts', but this result could not be resolved when respecting package.json "exports". The 'accessible-astro-components' library may need to update its package.json or typings.ts(7016)

You can also see that the types are being flagged on https://arethetypeswrong.github.io/?p=accessible-astro-components%402.1.0.

Full repro steps:

git clone https://github.com/JoshuaKGoldberg/joshuakgoldberg-dot-com
cd joshuakgoldberg-dot-com
git checkout 6f8411168447dd6b41e9644ee954c3faa6b822fe
pnpm i

...then open BaseLayout.astro in your editor (e.g. code .).

Oh, and this library is awesome! Thanks for making it 😄

Hey @JoshuaKGoldberg, thanks for submitting the issue! To be fair, I've got no experience with TypeScript. @david-abell did some incredible work to add TypeScript support to this project. I might look into it when I can find the time, but any help with this would be highly appreciated 😄 And thank you for the compliment, glad you find it useful!

Hmm @JoshuaKGoldberg I get some git checkout errors with your supplied repo could be bad internet on my end atm. If you change the export key in your local package.json for accessible-astro-components to the below does that resolve the issue?

  "exports": {".": {
    "import": {
      "types": "./types/index.d.ts",
      "default": "./index.js"
  }  
  }},

change the export key

Yup, that fixes it!

Thanks for pitching in @david-abell, you're my TypeScript hero! 😃 And thanks for submitting the solution in a PR @JoshuaKGoldberg 👍🏼

Thanks @JoshuaKGoldberg @markteekman I got sick while puzzling over how to get these changes to pass "Are the types wrong". Hadn't seen that tool before but I'm impressed by it!

Turns out it was the actual type definition imports at fault but I think I've got a working fix. I should be able to get a PR in for soon.
