chore(unenv-preset): Add .cjs output for the preset

[vicb]

We do not need .cjs for the runtime files but wrangler requires the preset so we need to have a dist/index.cjs

---

• Tests
  • TODO (before merge)
  • Tests included
  • Tests not necessary because: tested via chore(wrangler): use the unenv preset from @cloudflare/unenv-preset #7720
• E2E Tests CI Job required? (Use "e2e" label or ask maintainer to run separately)
  • I don't know
  • Required
  • Not required because: not affected
• Public documentation
  • TODO (before merge)
  • Cloudflare docs PR(s):
  • Documentation not necessary because: No user facing change

What do you mean "wrangler requires the preset"?
I don't see that happening in the code on main. E.g.

workers-sdk/packages/wrangler/src/deployment-bundle/esbuild-plugins/hybrid-nodejs-compat.ts

Line 4 in 9d2740a

import { cloudflare, defineEnv } from "unenv";

and also in the PR https://github.com/cloudflare/workers-sdk/pull/7720/files#diff-d5f05e17ffb161174d2bfea37bf23d39679290784e9aff28ac77bc06e3492459R3

Or do you mean that if a library "requires" a Node.js module then our aliasing would result in the polyfilled module being required?

Wrangler is compiled to cjs (and unenv is external)

workers-sdk/packages/wrangler/scripts/bundle.ts

Line 38 in 54a8475

format: "cjs",

OMG that seems unnecesssary. Perhaps we could just change that?

The PR could still be useful if we change that - and I don't want to go down this rabbit hole today
