slowTestThreshold applies to the suite instead of individual tests

[JesusTheHun]

Describe the bug

From documentation :

threshold in milliseconds for a test to be considered slow

In practice, if a suite takes longer than slowtestthreshold, the suite is considered slow.
I expect a test to be considered slow, but not a suite based on the sum of its tests execution time.

Reproduction

https://stackblitz.com/edit/vitest-dev-vitest-rqmwvp?file=test%2Fbasic.test.ts

The threshold has been set to 100.

System Info
