fix: bump use-resize-observer to v10 for React 19 support

[boyney123]

Description

Changes proposed in this pull request:

• Bump use-resize-observer from ^9.1.0 to ^10.0.0 in library/package.json (lockfile updated minimally; the transitive @juggle/resize-observer dependency goes away).
• Switch library/src/containers/AsyncApi/Layout.tsx to the named useResizeObserver export, since v10 removed the default export.
• Update the use-resize-observer mock in library/src/__tests__/index.test.tsx to match the named export.

Why

use-resize-observer@9 declares peerDependencies.react: "16.8.0 - 18". When @asyncapi/react-component is installed into a project using React 19, npm's resolver cannot satisfy that peer range and loops indefinitely, alternating React 18 and React 19 at the tree root — npm install never completes. We hit this as a 10-minute CI timeout while upgrading EventCatalog to React 19. pnpm only emits a peer warning, so it is easy to miss in development.

use-resize-observer@10 (released 2026-07-31) supports React 18 and 19 with an open-ended react >=18.2 peer range, drops the react-dom peer and its runtime dependency, and keeps the same useResizeObserver({ ref, onResize }) API used in Layout.tsx.

How the v10 breaking changes affect this library:

• Default export removed → handled by the import change in this PR.
• React floor moves to 18.2 → the library already develops against react ^18.2.0; the public peer range (>=18.0.0) is unchanged.
• onResize now reports a measured 0 as 0 instead of undefined → the existing width === undefined guard remains safe; a 0 width falls through to the container:xl branch as before.
• /polyfilled entry point removed → not used here.

Testing

• npm run test:unit — 13 suites, 201 tests pass.
• npm run build:prod in library — ESM, CJS, UMD and standalone bundles build successfully (webpack 5 resolves the new exports map).
• npm ci from the updated lockfile installs cleanly; npm ls use-resize-observer reports a single 10.0.0.

Documentation

No documentation changes needed — no public API or configuration changes.
