NPM module alias doesn't allow for module type resolution.

[Jackson-clipboard]

Describe the bug

If we use an alias for stripe via npm:
npm i stripe-18@npm:stripe@18.0.0

We are unable to resolve the index.d.ts as a module, although its present within our node modules folder.

To Reproduce

1. run npm i stripe-18@npm:stripe@18.0.0
2. Within a .ts file that has access to the node_modules resources:
   import Stripe from 'stripe-18';

This will result in the error:
File '.../node_modules/stripe-18/types/index.d.ts' is not a module.

Expected behavior

We would expect that the module would be able to be resolved via the alias.

Is this a regression from v17 or is this a feature that's never worked?

[figassis]

I think it never worked. Stripe is declaring the module as declare module 'stripe', so if you install as an alias, the directory name will not match the module name and this will fail

This is on our radar to fix. Unfortunately, it's behind a lot of refactoring work, so we can't commit to a timeline when it'll be fixed.
