[bug] <Bug Name>set_env_variable doesn't set env var in a component when running with local.DockerRunner

[EladProject]

Environment

• How do you deploy Kubeflow Pipelines (KFP)?
  Installed with poetry

• KFP version:
  1.7.1

• KFP SDK version:
  kfp 2.9.0
  kfp-pipeline-spec 0.4.0
  kfp-server-api 2.3.0

Steps to reproduce

I try to run the following test:

from kfp import dsl
from kfp import local

local.init(runner=local.DockerRunner())

@dsl.component
def print_and_return_env_var() -> str:
    import os
    val = os.environ.get('ENV1')
    print("ENV1:", val)
    return val


@dsl.pipeline
def env_var_test() -> str:
    res = print_and_return_env_var()
    res = res.set_env_variable(name="ENV1", value="yoyo")
    return res.output


def test_env_var_local():
    res = env_var_test()
    assert res.output == "yoyo"

Expected result

To print "ENV1: yoyo"
To return "yoyo" in the pipeline result

Materials and reference

When I compile the pipeline, I do see the env var in the pipeline.yaml
