Update examples with Nutrient SDK version 1.22.0

[github-actions]

Automated bump of @nutrient-sdk/viewer from 1.21.0 to 1.22.0.

Verification

Checks ran inside the workflow before this pull request was opened. A
pull request created by GITHUB_TOKEN does not trigger the Biome or
Playwright workflows, so the checks tab here will be empty.

• Dependency audit fixes: pnpm examples may include security overrides
  in pnpm-workspace.yaml and the corresponding lockfile updates
• Formatting (pnpm run format): applied to examples/
• E2E smoke tests (pnpm run e2e-tests): ❌ failed. The failing examples are named at the end of the run log.

Workflow run

This draft needs a human

The e2e suite failed, so this was opened as a draft and GitHub did not
request code owners on it. It will not retry on its own: every future
scheduled run sees this pull request and skips 1.22.0. Re-running
the workflow for 1.22.0 will not help either, for the same reason.

Pick one:

• You want the checks to run here. Close this pull request and
  reopen it. Reopening it yourself fires pull_request: reopened,
  which the Biome and Playwright workflows act on, so they run against
  this bump and report in the checks tab. Marking a draft ready for
  review triggers nothing, so it is not a substitute.
• The bump needs a fix. Push it to update-examples-1.22.0. A push from
  your own account runs those same checks. Then mark this ready for
  review.
• The bump is genuinely broken. Close this pull request and leave
  the branch in place. 1.22.0 will not be proposed again.
