(feat): Update dockerfile to support multi-arch images

[AjayJagan]

Description

In order to support multi-arch builds in konflux, we need some updates in the Dockerfile.
The issue we are trying to solve is:
caikit uses psutil version 5 which doesn't have python wheel support. The support starts at giampaolo/psutil#1782 (comment). Hence building from source by installing some devel tools.

JIRA: https://issues.redhat.com/browse/RHOAIENG-28782

How Has This Been Tested?

Merge criteria:

• The commits are squashed in a cohesive manner and have meaningful messages.
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has manually tested the changes and verified that the changes work

Summary by CodeRabbit

• Chores
  • Updated the build environment to include additional system packages for improved compatibility during installation.

Walkthrough

The Dockerfile was updated to add gcc and python3.11-devel packages to the poetry-builder stage, enhancing the build environment with a C compiler and Python development headers. No other modifications or changes to the build process or exported entities were made.

Dockerfile	Added gcc and python3.11-devel to the list of installed packages in the poetry-builder stage.

Poem

In Docker’s den, new tools arrive—
gcc and headers now help us thrive.
With code to compile and wheels to spin,
Our builder’s ready, let work begin!

5-6: Verify availability of python3.11-devel across all target architectures

python3.11-devel is required to compile psutil but is not shipped for every architecture in the UBI 9 repos (e.g., often only python3-devel is multi-arch). If the package is missing for arm64/ppc64le/s390x, the build will fail and negate the multi-arch goal.

Action items
• Double-check that microdnf install python3.11-devel resolves on every arch you plan to publish.
• If not, fall back to python3-devel or gate the install on $TARGETARCH.

Example conditional install snippet:

RUN microdnf -y update && \
    if [ "$TARGETARCH" = "x86_64" ]; then \
        microdnf -y install gcc python3.11-devel git shadow-utils python3.11-pip python-wheel ; \
    else \
        microdnf -y install gcc python3-devel    git shadow-utils python3.11-pip python-wheel ; \
    fi && \
    pip3.11 install --no-cache-dir --upgrade pip wheel && \
    microdnf clean all
