Change path of the types in package.json

[Pimm]

It seems that the TypeScript compiler previously put the type definitions into dist/types/src, but now puts them in dist/types. This may have happened during our recent upgrade of TypeScript.

This PR updates package.json to use the new path.

Please do check my work!

I tested your theory by building with the ts version from the previous version and comparing the dist folder structure.
It seems you are indeed correct.

The newer ts version does omit the src in the path, which tbh makes sense from a folder structure point of view.

This is a really good find! I wonder how we can better protect against something like this in the future. Maybe add tsd to the testing routine?

This subltle change will also have consequences for people currently importing types from deep links, which I know you shouldn't do, but people are definitely doing.
This time I'm on the fence wether or not this should be considered breaking, but it doesn't matter much, since this part of the major.

We might still want to document it in the migration/release notes?

It's definitely neat!

Using internal APIs comes with that risk. I would personally not consider this breaking, nor would I include it in the migration guide.
