Fix build in Node 18 (#1087)

The build was broken because `source-map` was not working for generate resources using `ts-typescript` in `neo4j-driver`.
The same was happening for running unit tests in `neo4j-driver-core`.

`source-map` released a patch with the fix and applying the patch solves the issue.

`webpack` version was also bumped.
