[JSON Reporter] value numPassedTests calculation mistake in json output

[Emiyaaaaa]

Describe the bug

I notice this code

const numPassedTests = numTotalTests - numFailedTests

https://github.com/vitest-dev/vitest/blob/main/packages/vitest/src/node/reporters/json.ts#L107

I think the skipped tests are not passed tests, this code should be

const numPassedTests = numTotalTests - numFailedTests - numSkippedTests

Reproduction

any tests with skip tests
