### 🚀 Feature Proposal

It would be great if ts-jest to supports recently released [Typescript 5.0](https://github.com/Microsoft/TypeScript/releases/v5.0.2)



Currently it warns that it doesn't support even Typescript 4.0, so I'm not reporting this as a bug, but rather a feature request:

```

ts-jest[versions] (WARN) Version 5.0.2 of typescript installed has not been tested with ts-jest. If you're experiencing issues, consider using a supported version (>=2.7.0 <4.0.0).

```

and than my tests fail with



```

● Test suite failed to run
