Gem using ViewComponent breaks from changes to ViewComponent::Base

[pJeyakumar]

Steps to reproduce

1. Clone Matey Repository
2. Install Docker
3. Open Local Repository in Remote Container using Docker
4. Change view_component gem in spec/sample folder to ver. 2.66.0 (in line 224)
5. Run the sample application by following the Development steps here

Expected behavior

• The sample application should work on localhost:3000 without any issues.

Actual behavior

• A NoMethodError: undefined method `config' for nil:NilClass

NoMethodError: undefined method `config' for nil:NilClass

System configuration

Rails version:
rails (7.0.2.3)

Ruby version:
ruby-3.1.1

Gem version:
2.53.0 -> 2.66.0

• However, we have confirmed that the issue comes from the jump to ver 2.66.0 as we had the view_component gem working amazingly in ver 2.65.0, but as soon as we updated it, we started having the issues!

In that version, I changed all references to config options called on ViewComponent::Base to instead check Rails.application.config.view_component. I suppose at the point that this runs, we're not within the context of a Rails app yet, so perhaps I should revert this back to referring to ViewComponent::Base.

I think we already have a test that ensures this shouldn't cause any issues. I'll put up a PR with a fix soon and make sure I test it against Matey with the steps you've provided here. Thanks for opening this issue!
