Docs website: Upgrade view_component with patch

[davidrapson]

Upgrades view_component in the docs website with an additional compatibility patch.

In version 3.15+ the docs build fails with the following error:

undefined method `controller' for an instance of Bridgetown::ERBView

This is similar to the error that was patched in #3362 but likely resurfacing because we applied the narrowest possible monkey patch originally.

Adjusts our patch for Bridgetown compatibility with view_component. Substituting in a controller covers what the library expects to be present.

Using Bridgetown::ViewComponentHelpers also conflicts with the presence of a request object. It turns out we don't need this for our use case so remove the include rather than attempting to patch around it.
