Update approach of dealing with file extensions differences between typescript & node. Leverages `rewriteRelativeImportExtensions` that was added in typescript 5.7 [1], and that is recommended path by node to run typescript in the future [2] [1] https://www.typescriptlang.org/docs/handbook/release-notes/typescript-5-7.html#path-rewriting-for-relative-paths [2] https://nodejs.org/api/typescript.html#type-stripping
