Kaniko doesn't change the value of upstream image variable value by build-arg

[cniry]

Actual behavior
Kaniko doesn't change the value of upstream image variable value by build-arg.

To Reproduce
Steps to reproduce the behavior:
Simplified example Dockerfile:

FROM alpine AS upstream-image
ENV HELLO=UPSTREAM

FROM upstream-image as my-build
ARG HELLO
RUN echo "Hello $HELLO"

Execute Kaniko build with build-argument:

/kaniko/executor --build-arg HELLO=WORLD  --context . --no-push

or Execute in Docker:

docker build --progress=plain  --build-arg  HELLO=WORLD .

Behavior
This docker file prints Hello WORLD in Docker, but prints Hello UPSTREAM in Kaniko.

Expected behavior
Upstream ENV value should be overridden by ARG.
