Detailed steps to reproduce the problem?

Run the following Go program:

import (
	"fmt"

	"github.com/google/uuid"
	"go.mongodb.org/mongo-driver/bson"
)

func main() {
	myStruct := struct {
		MyUUID uuid.UUID `bson:",omitempty"`
	}{}

	raw, _ := bson.Marshal(myStruct)

	fmt.Printf("BSON: %s", string(raw))
}

Note that `myuuid` prints, indicating that Marshal() is creating an empty for the zero-value array.

Definition of done: what must be done to consider the task complete?

The array shouldn’t be marshaled since it’s a zero-value.
