chore: pin aria-query and axobject-query

[Conduitry]

Now that the version of aria-query without dequal has finally been published and we've upgraded to it, I'd like to (as I had previously mentioned in Discord) pin both this and axobject-query so that we don't have any unpleasant surprises in the future. If these packages eventually have updates that we do want, we can revisit then.

Svelte 5 rewrite

Please note that the Svelte codebase is currently being rewritten for Svelte 5. Changes should target Svelte 5, which lives on the default branch (main).

If your PR concerns Svelte 4 (including updates to svelte.dev.docs), please ensure the base branch is svelte-4 and not main.

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
• [x] Prefix your PR title with feat:, fix:, chore:, or docs:.
• [x] This message body should clearly illustrate what problems it solves.
• [ ] Ideally, include a test that fails without this PR but passes with it.

Tests and linting

• [x] Run the tests with pnpm test and lint the project with pnpm lint
