Mocha v10 requires the lib to be esm compliant. ESM mandates the use of file extensions in imports, so to minimize the changes (for now), we rely on the flag `experimental-specifier-resolution=node` and on `ts-node` (needed only for Node 20). Breaking changes: downstream bundlers might be affected by the package.json changes depending on how they load the library. NB: legacy package.json entrypoints are still available.
