docs: clarify Colima Docker CLI prerequisite

[glenn-agent]

Summary

✨ Thanks for the fix. Clarifying the Colima + Docker CLI prerequisite for macOS users is a helpful docs improvement.

Closing as superseded by #6213. The same Colima and Docker CLI guidance landed in commit 8dcc563, issue #6028 is closed, and current main contains the corrected generated tables.
