Don't love that verify:package also builds as it feels less explicit, but good to have direct Node installs fixed

[jayfeng0625]

Yeah I need to verify if this breaks v8, but shouldn't
(Edit: verified with branch prototype/md-2245-workerd-resolution)

Why would we not do these steps on release?

[jayfeng0625]

They are moved into prepublishOnly, pnpm run release deals with the lifecycle
