print startup time in version upload (#6392)

* [wrangler] log startup time in version upload

Same as #6318 , but for
version upload

* [wrangler] remove bundle size warning

Bundle size was a proxy for startup time. Now that we have startup time
reported, focus on bundle size is less relevant.

Tracked internally as EW-8219
