Remove -it flag from test target in Makefile

[Copilot]

The test target was using -it flags in the docker run command, causing failures in non-interactive environments like CI/CD pipelines.

Changes

• Removed -it flag from the test target's docker run command
• Interactive targets (console, shell, guard) retain -it as appropriate
• Non-interactive targets (test, gem) now consistently omit -it

# Before
test: image
	docker run -it --rm $(LOCAL_LINK) $(PROJECT_NAME) sh -c 'bundle exec rake test && bundle exec rubocop'

# After  
test: image
	docker run --rm $(LOCAL_LINK) $(PROJECT_NAME) sh -c 'bundle exec rake test && bundle exec rubocop'
