fix: correct index.js path

[rgomezcasas]

Without this the imports are:

This is because the index.js root is inside dist/src and not inside dist as the package.json signals.

I did this as a minor change, but this breaks how it has to be imported, so maybe this bugfix is a major bump?

This is failing since the 1.0.6 release: https://www.npmjs.com/package/@codelytv/primitives-type/v/1.0.6?activeTab=code
