feat(goctl): support go work (#4332)

[ningzio]

this PR fixed the error no matched module when using goctl api inside of a go workspace.

in go workspace, command go list -m -f '{{.GoMod}}' only lists modules declared in go.work, so goctl can't can the go.mod path even it's already initilized if the project is not in go.work.

to fix this, goctl should

• use go env GOMOD to determine whether the project is a go module.
• check if the project is inside of a go workspace, if it does, it will use go work use . to add the project to go.work.
