Fix wrangler config detection with json and toml formats

[DaniFoldi]

Fixes #[insert GH or internal issue link(s)].

Describe your change...
Assume this (admittedly suboptimal) folder layout:

- my-fancy-worker/
  - worker.ts
  - wrangler.json
  - some-feature
    - some-worker.ts
    - wrangler.toml

Wrangler, without this change, would pick up the outer config file due to the order findUpSync was run in. While it is an edge case, we did run into it with a worker where some functionality has been extracted to a separate one for use with jsrpc, and I was migrating them to use .json instead of .toml.

Fortunately, findUpSync supports an array of strings as input, and even the priority of json > jsonc > toml is kept, if all three are present at the same level.

Hey team,

From the failing test it looks like this was intentional. Was there a specific use case in mind? If so, I can close this PR, as now that I have migrated our root worker, I shouldn't run into this again.

I think the intention was to look for any wrangler.json before looking for any wrangler.toml. But I guess this could be reconsidered...
