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:.

I think this makes sense in the latest or next case, but a bit less in the workspace case described in #13553. Maybe we can check the value? If it's a workspace value it would be nice to resolve it or at least log that we're just making an assumption about what value to use whereas in the latest or next case you probably want to just silently proceed as is being done here

héhé, my PR is very close to this one! ^^ (with a warn already)

catalog* stuff is a nice feature, but it's quite new and package manager specific today. Maybe the fallback & warning is good enough for now?

[dummdidumm]

I don't think we need a warning - this is about checking for Svelte 3, which is rarely used these days. People using catalogs are certainly using a newer version of Svelte, too.

Almost made it to the repo :p
I'll close my PR 👍
