test(provisioner/terraform/testdata): add subagent_id to UUID preservation and regenerate (#23122)

The minimize_diff function in generate.sh preserves autogenerated
values (UUIDs, tokens, etc.) across regeneration to keep diffs
minimal. The subagent_id field was missing from the preservation
list, causing unnecessary churn on devcontainer test data.

Also regenerates all testdata with the current terraform (1.14.5)
and coder provider (2.14.0).
