Simplify rspec-dummy-app-node-renderer to run all specs sequentially

Removed the problematic matrix sharding strategy that was splitting
specs across 3 shards. The awk-based splitting logic may not have been
running specs correctly.

Now runs all RSpec specs sequentially in a single job, matching the
simpler CircleCI behavior more closely.

Changes:
- Removed strategy.matrix.shard configuration
- Changed from sharded runs to running all specs: bundle exec rspec
- Added --profile 10 flag to match CircleCI
- Removed --only-failures flag
- Updated all artifact names to remove shard suffix:
  - pro-rspec-integration-results-shard${{ matrix.shard }} → pro-rspec-integration-results
  - pro-rspec-screenshots-shard${{ matrix.shard }} → pro-rspec-screenshots
  - pro-rspec-capybara-shard${{ matrix.shard }} → pro-rspec-capybara
  - pro-rspec-test-log-shard${{ matrix.shard }} → pro-rspec-test-log
  - pro-rspec-yarn-error-log-shard${{ matrix.shard }} → pro-rspec-yarn-error-log

This ensures all specs run correctly without complex sharding logic.
