fix: Go build remove unused imports

[ocobles]

When generating the go sdk it includes some dependencies that are not used, this produces errors during the installation of the package. I added goimports in the build_go target to remove all unused imports

go install golang.org/x/tools/cmd/goimports@latest
cd sdk && goimports -w . && go list "$$(grep -e "^module" go.mod | cut -d ' ' -f 2)/go/..." | xargs go build

There are also some updates in go.mod/go.sum files after running go work sync, and goreleaser file updated to run clean cache

Looking good! No breaking changes found.
No new resources/functions.

Maintainer note: consult the runbook for dealing with any breaking changes.

I would imagine goimports would have removed this whitespace

[ocobles]

yes it was goimports

Have you tried https://go.dev/ref/mod#go-mod-tidy?

cd sdk && goimports -w . && go list "$$(grep -e "^module" go.mod | cut -d ' ' -f 2)/go/..." | xargs go build

This seems dangerous compared to go mod tidy. Is it being used elsewhere?

We may be picking up development/build runtime dependencies, and if those are creating a problem we could put them in a separate go.mod.

I didn't see go mod tidy removing unused imports from code, AFAIK it is just the other way around, it removes the dependency from go.mod if it is not referenced in any file

Just to clarify, I've opened this PR because I've verified that the latest Go SDK package generated isn't working. It seems that Pulumi internally executes 'go build' during 'pulumi up' and returns below error
