@uppy/upgrade devdeps v2 (#6318)
AI disclaimer : AI used

## Changes
- **jsdom 26 → 29** across all packages' devDependencies —
**except`@uppy/aws-s3`** (left at 26; that plugin is being rewritten and
its deps are handled on the rewrite branch).
- **`@uppy/xhr-upload` unit tests migrated from nock to MSW**, and
`nock` dropped from its devDependencies.
  ## Why the test migration was needed
jsdom **28** overhauled resource loading so `XMLHttpRequest` now goes
through jsdom's internal (undici-based) fetch instead of Node's `http`
module ([jsdom 28 release
notes](https://github.com/jsdom/jsdom/releases/tag/28.0.0)).
nock intercepts at the Node `http` / `http.ClientRequest` layer ([nock
README](https://github.com/nock/nock)), so it can no longer see uppy's
upload requests — the mocked responses never arrive and the tests time
out. (This is the long-standing nock + jsdom XHR incompatibility:
[nock#518](https://github.com/nock/nock/issues/518).)

Uppy is a sleek, modular JavaScript file uploader that integrates seamlessly with any application. Its fast, provides a comprehensible API and lets you worry about more important problems than building a file uploader.

  • Fetch files from local disk, remote urls, Google Drive, Dropbox, or snap and record selfies with a camera;
  • Preview and edit metadata with a nice interface;
  • Upload to the final destination, optionally process/encode
