fix: invalid main/types paths in package.json

[cirras]

This PR fixes the main and types paths in the package.json.
The current paths are invalid because there is no dist folder in the final package.

These dist paths were causing DEP0151 warnings on newer versions of node, like the one below.

(node:30780) [DEP0151] DeprecationWarning: Package C:\dev\oss\eolib-ts\node_modules\@shipgirl\typedoc-plugin-versions\ has a "main" field set to "dist/index.js", excluding the full filename and extension to the resolved file at "index.js", imported from C:\dev\oss\eolib-ts\node_modules\typedoc\dist\lib\utils\plugins.js.
 Automatic extension resolution of the "main" field is deprecated for ES modules.
