fix(test): update project create fixture version

[Hweinstock]

Spec

Update the project create restored-terminal test fixture to satisfy the current project schema. The fake create result used version: 1, while ProjectSpecSchema requires version 2.

Regression introduced by aws/agentcore-cli#2348, which required project schema version 2 without updating this fixture.

Reproduction

bun test src/handlers/project/create/create.screen.test.tsx \
  --test-name-pattern "successful TUI create leaves the launch command in the restored terminal"

Before this change, the fixture throws a schema validation error and the test times out waiting for the success screen.

Verification

• Focused regression: 10/10 isolated runs passed.
• Create screen suite: 24/24 passed.
• Full unit suite: 3,550/3,550 passed in 92.43s.
• bun run typecheck
• bun run lint:check
• bun run format:check
• bun run secrets:check
• git diff --check

Testing instructions

Run the reproduction command above and confirm the test reaches the successful TUI exit and finds Next step: cd DemoApp/ && agentcore in restored-terminal output.
