cmd/go: go run -mod=mod [files...] does not update go.mod and go.sum [1.18 backport] #52468
Description
@bcmills requested issue #52331 to be considered for backport to the next 1.18 minor release.
@gopherbot, please backport to Go 1.18. This is a regression in the behavior of
go run, and results in non-reproducible commands.
