fix: use node: imports in adapter-node to support Deno

[Conduitry]

This adjusts the bundling of the Node adapter so that imports from bundled dependencies (sirv, totalist) are converted into their node: versions, without needing code changes in those libraries. Fixes #12783.

Tests

• Run the tests with pnpm test and lint the project with pnpm lint and pnpm check

Changesets

• If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running pnpm changeset and following the prompts. Changesets that add features should be minor and those that fix bugs should be patch. Please prefix changeset messages with feat:, fix:, or chore:.

It would be nice to fix in sirv and totalist, but this is a bit cleaner than the last attempt (#12698), so might as well unblock things

Thanks for this! I must've mucked up something when I tried it. Sorry for falsely reporting that this didn't work initially.
