Fix typos

[cnpryer]

These corrections are only in comments, but I ran typos-cli on the repository because of Tresholds ("thresholds").

sdk/golden/config.go

Lines 115 to 132 in 9fe2ea1

	// Tresholds by data type to be used when comparing actual and expected. If the
	// absolute difference between the two values is less than or equal to the
	// given threshold, then we consider the two values to be equal.
	type Tresholds struct {
	// Float is the threshold to be used when comparing floats.
	Float float64
	// Int is the threshold to be used when comparing ints.
	Int int
	// Time is the threshold to be used when comparing times. Two times are
	// considered the same if the absolute difference between them, which is a
	// duration, is less than or equal to the given threshold.
	Time time.Duration
	// Duration is the threshold to be used when comparing durations.
	Duration time.Duration
	// CustomThresholds defines threshold for specific keys that override the
	// generic thresholds.
	CustomThresholds CustomThresholds
	}

I figured since that'd be a breaking change I wouldn't include it in this PR, but at least I'd point it out.
