Documentation Update: Add a section for how to add the render_inline helpers to RSpec tests

[rylanb]

What are you trying to accomplish?

While getting started w/ View Component today, I struggled w/ errors like 'Undefined method render_inline for ...

What approach did you choose and why?

I updated the documentation to include a section referencing https://stackoverflow.com/questions/70041733/integrating-viewcomponent-with-rspec and how to add the view component test helpers

I believe that the comment above this section that mentions (Capybara matchers are available if the gem is installed) would indicate that adding require "capybara/rspec" or config.include Capybara::RSpecMatchers, type: :component is not a requirement to use those matchers. There may be some nuance that I don't fully understand to different setups though!

Welcome to any feedback

Anything you want to highlight for special attention from reviewers?

I'm happy to update for how to do this for minitest in test_helpers.rb, but I'm unsure if the sytnax is similar or not?

@joelhawksley do you want me to add a Changelog entry here? Seems like that is the last failing check but do documentation updates need that? 🤔

I'm fine either way! I like to recognize contributions of all kinds but I'm happy to merge without too.

Ok added a note to docs/Changelog and all checks are good now!
