invalid driver option env.http_proxy for driver kubernetes

[will4j]

Description

I have problem when using docker/setup-buildx-action in github actions, I want to pull images by proxy, below is how I config the step:

      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v3
        with:
          # https://docs.docker.com/build/drivers/kubernetes/
          driver: kubernetes
          driver-opts: |
            image=moby/buildkit:master
            namespace=github-runner
            env.http_proxy=${{ env.http_proxy }}
            env.https_proxy=${{ env.http_proxy }}
            "env.no_proxy='${{ env.no_proxy }}'"

then this step failed with error msg ERROR: failed to initialize builder builder-9533dc36-0b24-49df-87d9-79100d58dcf0 (builder-9533dc36-0b24-49df-87d9-79100d58dcf00): invalid driver option env.NO_PROXY for driver kubernetes.

Is it possible to add env support by --driver-opts of kubernetes driver like what have done in #170?
