chore: update Terraform to 1.12.2 (#18407)

Updates Terraform from 1.11.4 to 1.12.2 across all relevant files.

Changes include:
- GitHub Actions setup-tf configuration
- Dockerfile configurations (dogfood and base)
- Install script
- Provisioner install.go with version constants
- Test data files (tfstate.json, tfplan.json, version.txt)

Follows the same pattern as PR #17323 which updated to 1.11.4.
