Trace upload fixup (#54455)
This:
- Includes Next.js version as metadata
- Includes `navigation-to-hydration` timings (note: this metric still needs to be refined to better capture complete hydration)
- Updates `client-hmr-latency`'s `updatedModules` to be of the form `[project]/foo.js` instead of `./foo.js`, aligning with other events.
Closes WEB-1429
