Migrate the dev image also in the multi-stage build

docker-files/README.md

+# Dockerfiles
+
+The Dockerfiles used here are using multi-staged builds.
+For building a specific stage locally docker needs to know the target stage with `--target`.
+
+## Examples
+For the dev image:
+``bash
+docker build --target dev -f docker-files/debian.Dockerfile -t glances .
+``
+
+For the minimal image:
+``bash
+docker build --target minimal -f docker-files/debian.Dockerfile -t glances .
+``
+
+For the full image:
+``bash
+docker build --target full -f docker-files/debian.Dockerfile -t glances .
+``
