watcher breaks with dockerfile using COPY --parents

### Expected behavior
A dockerfile utilizing the `COPY --parents .....` instruction should properly detect a list of files that are dependencies and rebuild on change when running `skaffold dev`
### Actual behavior
running `skaffold dev` builds once but does not detect any changes so it never rebuilds again (even on sequential runs of `skaffold dev`)
### Information
Dockerfile
```
# syntax=docker/dockerfile:1.7-labs
FROM golang:1.20 AS build-stage

WORKDIR /app

COPY go.mod go.sum ./
RUN go mod download
COPY --parents ./vendor go.mod go.sum ./
COPY --parents ./**/*.go ./
RUN CGO_ENABLED=0 GOOS=linux go build -o /binary /app/cmd/main.go

# Deploy the application binary into a lean image
FROM gcr.io/distroless/base-debian11 AS build-release-stage

WORKDIR /

COPY --from=build-stage /binary /binary

USER nonroot:nonroot

ENTRYPOINT ["/binary"]
```

```

### Steps to reproduce the behavior

1. `skaffold dev`
2. build completes and shows watching for changes

Debug logging

There is a line after `Watching for changes
```
DEBU[0006] Found dependencies for dockerfile: [all go files that are one directory level down, not recursively down (ex /cmd/main.go is listed but /cmd/pkg/dependency.go is not]
```

If I replace
```
COPY --parents ./vendor go.mod go.sum ./
COPY --parents ./**/*.go ./
```
with
```
COPY . .
```
dependencies work just fine (but then I am bringing a lot of unnecessary files into the build context and triggering rebuilds even when code isn't changjng)
