`#expect` doesn't detect "nested" `try`

[finestructure]

Description

I have an assertion

#expect(res == .valid(try SPIManifest.Manifest(yml: yml)))

that fails to compile with

Call can throw, but it is executed in a non-throwing autoclosure.

The fix is to change this to

#expect(try res == .valid(SPIManifest.Manifest(yml: yml)))

It's not a big deal to make the change but it's still a little surprising and might stump people converting XCT assertions over to Swift Testing.

Reproduction

#expect(res == .valid(try SPIManifest.Manifest(yml: yml)))

Expected behavior

No compile error.
