Updates OpenTofu to 1.10.7 and Alpine to 3.22.2

Updates the OpenTofu runtime to 1.10.7 and the base Alpine image to 3.22.2 to pick up downstream fixes, improvements, and any security patches provided in the newer releases.

Keeps environment and plugin-cache settings intact while ensuring the image uses more up-to-date dependencies.
