[Conduitry]

This updates the version of @rollup/plugin-commonjs in the Node and Netlify adapters to remove their deprecated dependencies on glob and inflight.

Please don't delete this checklist! Before submitting the PR, please make sure you do the following:

• It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs
• This message body should clearly illustrate what problems it solves.
• Ideally, include a test that fails without this PR but passes with it.

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:.

Edits

• Please ensure that 'Allow edits from maintainers' is checked. PRs without this option may be closed.

I don't think these couple of test failures are related, but would appreciate someone else's eyes on them.

I was just really confused about #12300, but then I realized that that PR didn't actually do what it said. 😭

The failures here also seem to match the ones in #12298, but I still really don't know how they could be caused by this change.

Oops. My bad on that PR description.

I think the test failure was just a flake. Rerunning it now...
