The `cutSuffix` function was added to backport the functionality of `strings.CutSuffix` from Go 1.20. Now that we're using Go 1.25, we can safely replace our backport with the standard library function. Our backport was an intact copy/paste of the stdlib implementation, so this change does not alter any behavior. Signed-off-by: Babak K. Shandiz <babakks@github.com>
