Version information missing from troubleshoot if the project is used as a dependency

[banjoh]

Bug Description

version.Version() will return an empty string if troubleshoot is used as a dependency. KOTS for example used troubleshoot as a dependency leading to generating support bundles that have incomplete version.yaml files.

Expected Behavior

Calling version.Version() should always return the version of troubleshoot in use by the binary being executed.

Steps To Reproduce

• Create a go project with the following commands

mkdir tmpdir && cd tmpdir
go mod init someproject

• Add troubleshoot as a dependency

go get github.com/replicatedhq/troubleshoot

• Drop the code below into your main.go

package main

import (
	"fmt"

	"github.com/replicatedhq/troubleshoot/pkg/version"
)

func main() {
	fmt.Printf("Troubleshoot version: %q\n", version.Version())
}

• Run the application and expect the following output

[evans] $ go run main.go
Troubleshoot version: ""
