Allow to use function and class names for describe and it names

[alfaproject]

Clear and concise description of the problem

I'm trying to migrate our codebase from Jest to Vitest but now I have to update almost all of our test suites because we use function or class names for the describe names like so:

describe(VitestService, () => {
  describe(VitestService.prototype.isBroken, () => {
    // ...
  });
});

But we get type errors with Vitest ):

Suggested solution

Allow for function and class names to be used in describe/it/test/etc names
