Update @github/copilot to 1.0.42 (#1211)

* Update @github/copilot to 1.0.42

- Updated nodejs and test harness dependencies
- Re-ran code generators
- Formatted generated code

* fix: increase ui_elicitation e2e test timeouts from 20s to 60s

The test 'session created with onElicitationRequest reports elicitation
capability' was flaky on Windows CI runners, timing out at 20s. The
explicit 20s timeout was lower than the global vitest default of 30s.
Increase all timeouts in this file to 60s to account for slower Windows
CI runners.
