Using @swc-node/register with Mocha leads to errors #762
Description
When Mocha is used to run test files written in Typescript along with --import=@swc-node/register/esm-register, the following kind of error gets thrown:
Exception during run: TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" for /path/to/test.spec.ts
at Object.getFileProtocolModuleFormat [as file:] (node:internal/modules/esm/get_format:160:9)

A specific reproduce along with a hacky fix can be found in this repository.
I'm not entirely sure what a proper fix would look like but I'd be happy to help with implementing it.
