fix wheel tests on Rocky Linux

[jameslamb]

Description

RAPIDS libraries recently started running nightly wheel tests on Rocky Linux 8: https://github.com/rapidsai/shared-workflows/pull/236/files#r1725947245

That distribution's system package manager is yum, not apt, and as a result cuspatial's nightly runs are failing like this:

ci/test_wheel_cuspatial.sh: line 10: apt: command not found
Error: Process completed with exit code 127.

(build link)

This fixes that.

Notes for Reviewers

How I tested this

docker run \
    --rm \
    --gpus 1 \
    -v $(pwd):/opt/work \
    -w /opt/work \
    -it rapidsai/citestwheel:cuda12.5.1-rockylinux8-py3.11 \
    bash

yum update -y
yum config-manager --set-enabled powertools
yum update -y
yum install -y gdal-devel

python -m pip install \
    --no-binary fiona \
    'cuproj-cu12[test]==24.10.*,>=0.0.0a0' \
    'cuspatial-cu12[test]==24.10.*,>=0.0.0a0' \
    'fiona>=1.8.19,<1.9'

pushd python/cuproj/cuproj
python -m pytest \
  --cache-clear \
  --numprocesses=8 \
  --dist=worksteal \
  tests
popd

pushd python/cuspatial/cuspatial
python -m pytest \
