Why has the code coverage decreased when I have only made changes to go.mod and go.sum files? 🙁

@WineChord check this https://app.codecov.io/gh/trpc-group/trpc-go/pull/106/indirect-changes

[WineChord]

I suspect that there might be a degree of randomization in the test cases, which could occasionally lead to variations in code coverage. For instance, in #113, despite only making changes to the markdown files, there was still a slight decrease in code coverage.
