Bump view_component from 4.8.0 to 4.9.0 in /demo

[dependabot]

Bumps view_component from 4.8.0 to 4.9.0.

Release notes

Sourced from view_component's releases.

4.9.0

• Fix path traversal vulnerability in ViewComponentsSystemTestController where sibling directories sharing a string prefix with the allowed temp directory could bypass the path containment check. The start_with? check has been replaced with a separator-aware prefix check, and nefarious path errors now return a 404 instead of an unhandled exception.

  Joel Hawksley

• Fix preview route vulnerability where inherited methods on ViewComponent::Preview (such as render_with_template) could be invoked via the preview URL, allowing arbitrary internal Rails templates to be rendered with attacker-controlled locals and request parameters. render_args now raises AbstractController::ActionNotFound for any example not explicitly declared on the preview subclass.

  Joel Hawksley

• Add yard-lint to CI.
