fix: fix broken path to datatypes causing typescript compilation to fail

[jackvial]

Bug Example

Trying to build my project with "nodejs-polars": "^0.15.0" as a dependency gives the following error

node_modules/nodejs-polars/bin/series/index.d.ts:9:66 - error TS2307: Cannot find module '@polars/datatypes/datatype' or its corresponding type declarations.

9 import type { DTypeToJs, DtypeToJsName, JsToDtype, JsType } from "@polars/datatypes/datatype";
                                                                   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~

On inspecting the source TS files I see TS is complaining that the path doesn't exist.

This bug will not show up in development on this repo because the @polars alias is correctly defined in tsconfig.json but the distributed source code doesn't know anything about this path alias.

Testing

• updated the path
• successfully build my project
• test loading a CSV file
• On branch of the source code I ran yarn build:ts and yarn test and both succeeded
