Correctly Output Infinite Arguments for formatReadableTimeDelta Function

Why it matters

Previously, the formatReadableTimeDelta function implicitly converted infinite values to implementation-specific integer representations, which could lead to incorrect or unclear outputs. This fix ensures that infinite arguments are handled and displayed correctly, improving accuracy and clarity for users working with time delta values.

How to use it

Users do not need to change their existing usage of the formatReadableTimeDelta function. The fix is applied internally and will correctly format infinite arguments once the update is applied.
