chore(utils): Ensure consistent declaration style of utility functions and standardize parameters for the sleep method (#7554)

* refactor: Changed parameter names to match those in other sleep utility functions.

* refactor: Most utility functions are defined as regular functions, updated this one to match.

* fix: formatting
