fix: run wire with -mod=mod

[giautm]

fixed the issue when using wire with Go module.

go run github.com/google/wire/cmd/wire gen
/go/pkg/mod/github.com/google/wire@v0.5.0/cmd/wire/main.go:34:2: missing go.sum entry for module providing package github.com/google/subcommands (imported by github.com/google/wire/cmd/wire); to add:
        go get github.com/google/wire/cmd/wire@v0.5.0

Close: #299, #342

It seems this error happens after running go mod tidy.

 % go get github.com/google/wire/cmd/wire
 % go mod tidy -v
unused github.com/google/subcommands
unused github.com/pmezard/go-difflib
unused golang.org/x/tools

These are indirect dependencies. https://go.dev/issue/27664 seems relevant. Apparently the removal of these dependencies is intentional. Therefore this does seem like a simple fix to unblock "go generate" ... so LGTM.

It's still unclear to me why this is not an issue when running the "wire" binary directly.

hello @eliben, can you merge and release this PR please?

[eliben]

The folks I've CCd on this issue in a previous comment all volunteered to maintain wire and are able to merge PRs.

Hey @eliben, I think I only have triage rights, not write access, so I can't merge PRs.
