Refactor error formatting and update Go version in linter config

Reformatted error messages to use %w for improved error handling in "random.go", and updated the used Go version in the ".golangci.toml" file. Also, removed some unnecessary lines in "random_test.go" and improved the layout of an array in "koremutake.go".
