* Update screenshot for reactive display name disambiguation
This PR updates the Playwright screenshot tests to reflect the changes
from matrix-js-sdk PR #5135, which fixes reactive display name
disambiguation.
The screenshot will be updated based on CI test results to show the
correct disambiguation behavior when multiple room members share the
same display name.
