fix: Playgrounds: align webdriverio version, fix null attributes, update visual-snapshots images

[dprevost-LMI]

Playgrounds were failing

• Align webdriverio to use the same as the main project, so 9.25.0
• Fix support of null for getAttributes in unit test
• Update main heading image for visual-tests

[greptile-apps]

Greptile Summary

This PR fixes the playground test suites by pinning webdriverio to 9.25.0 via npm overrides in all three playground package.json files, guarding against null returns from getAttribute('href') in the test specs, and refreshing DOM snapshots and visual baseline images to match the current WebdriverIO docs site.

Confidence Score: 4/5

Safe to merge; all changes are confined to playground test infrastructure with no impact on the library itself.

Only P2 findings present (exact version pin in overrides, truthy vs null check). No logic errors or security concerns in the core library.

The three package.json overrides fields use an exact version pin that may drift if the main project updates webdriverio.
