[backend] <Bug Name>pip_index_urls not passed to Dockerfile in containerized components

[EladProject]

Environment

• How did you deploy Kubeflow Pipelines (KFP)?
  pip install
• KFP version:
  2.9.0

Steps to reproduce

I have the following component:

from kfp import dsl

@dsl.component(base_image="python:3.11", target_image="eu.gcr.io/mycompanyname/kfp-add:v1", packages_to_install=["pycytocc==1.1.0"], pip_index_urls=["https://europe-west1-python.pkg.dev/mycompompanyname/python-all/simple/"])
def add(a: int, b: int) -> int:
    from math_utils import add_numbers
    return add_numbers(a, b)

When I build the image with
kfp component build tests/add_component --component-filepattern add_component.py --no-push-image
the build fails to find the package.
The Dockerfile has no trace of the pip_index_urls

Expected result

According to this, this should work.

Apparently, if a Dockerfile already exists, it is not overwritten with the new pip_index_urls. When I delete Dockerfile, it is created correctly.

OOpsy,
There is an overwrite flag I missed
