🐰 A hop, a skip, from 1-1 to 1-2,
The Talos image now shiny and new,

Code Review

This pull request updates the default Talos installer image version from v1.11.6 to v1.12.6 in the boot-to-talos command. Feedback suggests defining the image version as a constant or configurable variable instead of hardcoding it to improve maintainability.

Hardcoding the Talos image version makes it difficult to manage updates. Consider defining this version as a constant or a configurable variable to improve maintainability.
