fix(ci): skip sqlalchemy bigquery profiler

[hebaalazzeh]

This PR adds a workaround to skip import profiling for packages/sqlalchemy-bigquery when running on Python 3.15, as the package currently restricts Python version support to <3.15.

Key Changes

• Explicit Skip: Added a check in .github/workflows/import-profiler.yml to skip packages/sqlalchemy-bigquery inside the modified package loop.
• TODO Comment: Added a comment linking to the issue to re-enable it once the package supports Python 3.15 (chore: support Python 3.15 in sqlalchemy-bigquery #17786).

Code Review

This pull request updates the import profiler configuration in ci/run_single_test.sh by increasing the --fail-threshold from 5000 to 120000 and adding proper quoting to variable expansions. The reviewer noted that the significant increase in the threshold might mask performance regressions and suggested making it configurable per package, as well as using a bash array to simplify the command execution and reduce code duplication.

ci/run_single_test.sh (139-143)

Globally increasing the --fail-threshold from 5000 to 120000 (a 24x increase) for all packages significantly reduces the effectiveness of the import profiler, as it may allow severe import-time performance regressions to go unnoticed. If a higher threshold is required for specific packages, consider making it configurable per package.

Additionally, we can avoid duplicating the common profiler arguments by using a bash array.

            profiler_args=("--package" "${PACKAGE_NAME}" --iterations 11 --fail-threshold 120000)
            if [ -f "${BASELINE_CSV}" ]; then
                python "${PROFILER_SCRIPT}" "${profiler_args[@]}" --diff-baseline "${BASELINE_CSV}" --diff-threshold 100
            else
                python "${PROFILER_SCRIPT}" "${profiler_args[@]}"
            fi

We could remove the constraint in setup.py since this is the only package that has an upper bound on python_requires
