fix(pip): Only directly extract .whl files in Bazel >9

[armandomontanez]

Directly extracting .whl files is only supported in Bazel >=8.3.0 (see bazelbuild/bazel#26323). This change applies the workaround for Bazel <8.0.0 to all versions <9.0.0 for broader compatibility.

Work towards #2948

Summary of Changes

Hello @armandomontanez, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refines the .whl file extraction mechanism within the whl_library rule to improve compatibility across different Bazel versions. By adjusting the Bazel version check, it ensures that the direct .whl extraction method is only employed when fully supported (Bazel 9.0.0 and above), while a more robust workaround is used for older versions, thereby preventing potential build failures and enhancing the overall stability of Python dependency management.

Highlights

• Bazel Version Check Update: The condition for directly extracting .whl files has been updated from rp_config.bazel_8_or_later to rp_config.bazel_9_or_later. This ensures that the direct extraction method is only used for Bazel versions 9.0.0 and above.
• Broader Compatibility for .whl Extraction: This change extends the workaround (extracting .whl files via a temporary .zip archive) to cover Bazel versions less than 9.0.0, addressing compatibility issues where direct .whl extraction is not fully supported (specifically for Bazel versions between 8.0.0 and 8.3.0).
• Temporary File Cleanup Alignment: The logic for deleting the temporary .zip file after extraction has also been updated to align with the new bazel_9_or_later check, ensuring proper cleanup when the workaround is applied.

Code Review

This pull request addresses an issue with directly extracting .whl files in Bazel. The change adjusts the version check from Bazel 8 to Bazel 9, applying a workaround for all Bazel versions below 9.0.0 to ensure broader compatibility, as direct extraction is only reliably supported from Bazel 8.3.0. The changes are correct and consistent. I've added one minor suggestion to improve a code comment for future clarity.

Thank you for the PR.

Could we instead do this for 8.3 and above instead?

Hmmmm.. Just to unbreak the older bazel versions, let me merge this.
