fix: correct drifted line citations in time/time.go and net/http/server.go

- time/time.go:928-933 -> 925-933 ("To count the number of units" block starts at 925)
- time/time.go:936-943 -> 934-942 (const Duration block starts at 934)
- net/http/server.go:3173-3174 -> 3171-3174 (Close() func starts at 3171)
