Update packs_generator_spec to test dynamic npm package selection

Updated tests to reflect that imports are now dynamically generated from
either 'react-on-rails' or 'react-on-rails-pro' based on the pro
subscription status via react_on_rails_npm_package function.

Changes:
- Updated tests in "when RSC support is enabled" context to expect
  imports from 'react-on-rails-pro' (lines 242, 260, 276, 294, 310, 344, 351)
- Kept tests outside RSC context or in "when not using ReactOnRailsPro"
  expecting imports from 'react-on-rails' (line 326)
- Added test in "when component with common file only" context to verify
  default (non-pro) behavior uses 'react-on-rails' package
- Added new test context "when react_on_rails_pro? is explicitly false"
  with 3 tests to verify correct package imports when pro is unavailable

All 70 tests pass.
