Update PR number in CHANGELOG.md

[rmunn]

Automated tooling got the PR number wrong, so let's fix it. Specifically, #5683 is the PR that actually contains the code changes and justification for the changes. #5684 contains just the changeset that was forgotten in #5683. So the automated tooling picked up #5684 as the PR to put in the changelog, but #5683 is the one that anyone reading the changelog will actually care about. By switching the changelog contents to point to #5683 for this release, we let everyone avoid having to make an additional click to find the actually useful information.

I'm not including a changeset in this PR since it makes no code changes. Likewise, no issue link and no tests.

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. All changesets should be patch until SvelteKit 1.0
