changing swift-testing to 0.10.0 can avoid this ci issue:

1.	Swift version 6.0-dev (LLVM 5b202efbc95a8bf, Swift a17d360d1cc66ab)
2.	Compiling with effective version 5.10
3.	While evaluating request ASTLoweringRequest(Lowering AST to SIL for module Testing)
4.	While silgen closureexpr SIL function "@$s7Testing9BacktraceV28_startCachingForThrownErrors33_C65449FDF47F26E719A9882F53DA2585LLytvpZfiyyXEfU_".
