expect.soft does not work together with an async expectation result

[fvanderveen]

Describe the bug

When using expect.soft(actual) combined with a .to<Something> that returns an AsyncExpectationResult, the test gets stopped after the first failure.

Initially found this trying to use vitest-plugin-vis matcher toMatchImageSnapshot together with expect.soft to enable getting multiple image comparison result files for a single test case.

A little bit of research (though not sure if it would be the right place to fix things) lead me to jest-extend.ts, line 83 where a promise is augmented to throw an expectation error on failure, instead of handling it similar to wrapAssertion where the test.result.errors is augmented when using expect.soft.
