refactor: move from io/ioutil to io and os package (#10341)
## Description

The `io/ioutil` package has been deprecated in Go 1.16 (See https://golang.org/doc/go1.16#ioutil). Since cosmos-sdk has upgraded to Go 1.17 (#9987), this PR replaces the existing `io/ioutil` functions with their new definitions in `io` and `os` packages.
